Commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back
type") introduced a new probe callback to convert i2c init routines to
not take an i2c_device_id parameter. Now that all in-tree drivers are
converted to the temporary .probe_new() callback, .probe() can be
modified to match the desired prototype.
Now that .probe() and .probe_new() have the same semantic, they can be
defined as members of an anonymous union to save some memory and
simplify the core code a bit.

The probe function doesn't make use of the i2c_device_id * parameter so
it can be trivially converted.

msm-fixes for v6.3-rc2
- Fix for possible invalid ptr free in submit ioctl syncobj cleanup path.
- Synchronize GMU removal in driver teardown path
- a5xx preemption fixes
- Fix runpm imbalance at unbind
- DPU hw catalog fixes:
- set DPU_MDP_PERIPH_0_REMOVED for sc8280xp as this is another chipset
where the PERIPH_0 block of registers is not there
- fix the DPU features supported in QCM2290 by comparing it with the
downstream device tree
- fix the length of registers in the sc7180_ctl from 0xe4 to 0x1dc
- fix the max mixer line width for sm6115 and qcm2290 chipsets in the
DPU catalog
- fix the scaler version on sm8550, sc8280xp, sm8450, sm8250, sm8350
and sm6115. This was incorrectly populated on the SW version of the
scaler library and not the scaler HW version
- Drop dim layer support for msm8998 as its not indicated to be
supported in the downstream DTSI
- fix the DPU_CLK_CTRL bits for msm 8998 sspp blocks
- Use DPU_CLK_CTRL_DMA* prefix instead of DPU_CLK_CTRL_CURSOR*
for all chipsets for the DMA sspp blocks
- fix the ping-pong block base address for sc7280 in the DPU HW catalog
- Fix stack corruption issue in the dpu_hw_ctl_setup_blendstage() function
as it was causing a negative left shift by protecting against an invalid
index
- Clear the DSPP reservations in dpu_rm_release(). This was missed out and
as as result the DSPP was not released from the resource manager global
state.

In ioctl(KD_FONT_OP_GET_TALL), userland tells through op->height which
vpitch should be used to copy over the font. In con_font_get, we were
not checking that it is within the maximum height value, and thus
userland could make the vc->vc_sw->con_font_get(vc, &font, vpitch);
call possibly overflow the allocated max_font_size bytes, and the
copy_to_user(op->data, font.data, c) call possibly read out of that
allocated buffer.
By checking vpitch against max_font_height, the max_font_size buffer
will always be large enough for the vc->vc_sw->con_font_get(vc, &font,
vpitch) call (since we already prevent loading a font larger than that),
and c = (font.width+7)/8 * vpitch * font.charcount will always remain
below max_font_size.

A recent commit added back the calls top stop tx and rx to shutdown()
which had previously been removed by commit e83766334f96 ("tty: serial:
qcom_geni_serial: No need to stop tx/rx on UART shutdown") in order to
be able to use kgdb after stopping the getty.
Not only did this again break kgdb, but it also broke serial consoles
more generally by hanging TX when stopping the getty during reboot.
The underlying problem has been there since the driver was first merged
and fixing it is going to be a bit involved so simply stop calling the
broken stop functions during shutdown for consoles for now.

The 8250 handle_irq callback is not just called from the interrupt
handler but also from a timer callback when polling (e.g. for ports
without an interrupt line). Consequently the callback must explicitly
disable interrupts to avoid a potential deadlock with another interrupt
in polled mode.
Fix up the two paths in the freescale callback that failed to re-enable
interrupts when polling.

REGMAP is a hidden (not user visible) symbol. Users cannot set it
directly thru "make *config", so drivers should select it instead of
depending on it if they need it.
Consistently using "select" or "depends on" can also help reduce
Kconfig circular dependency issues.
Therefore, change the use of "depends on REGMAP" to "select REGMAP".

UARTCTRL_SBK is asserted
According to LPUART RM, Transmission Complete Flag becomes 0 if queuing
a break character by writing 1 to CTRL[SBK], so here need to skip
waiting for transmission complete when UARTCTRL_SBK is asserted,
otherwise the kernel may stuck here.
And actually set_termios() adds transmission completion waiting to avoid
data loss or data breakage when changing the baud rate, but we don't
need to worry about this when queuing break characters.

When neither "no_read_workqueue" nor "no_write_workqueue" are enabled,
tasklet_trylock() in crypt_dec_pending() may still return false due to
an uninitialized state, and dm-crypt will unnecessarily do io completion
in io_queue workqueue instead of current context.
Fix this by adding an 'in_tasklet' flag to dm_crypt_io struct and
initialize it to false in crypt_io_init(). Set this flag to true in

Some boards might use USB-A female connector for USB ports, however,
the port could be connected to a dual-mode USB controller, making it
also behaves as a peripheral device if male-to-male cable is connected.
In this case, the dts looks like this:
&usb0 {
status = "okay";
dr_mode = "otg";
usb-role-switch;
role-switch-default-mode = "host";
};
After boot, dwc2_ovr_init() sets GOTGCTL to GOTGCTL_AVALOVAL and call
dwc2_force_mode() with parameter host=false, which causes inconsistent
mode - The hardware is in peripheral mode while the kernel status is
in host mode.
What we can do now is to call dwc2_drd_role_sw_set() to switch to
device mode, and everything should work just fine now, even switching
back to none(default) mode afterwards.

In the unbind callback for f_uac1 and f_uac2, a call to snd_card_free()
via g_audio_cleanup() will disconnect the card and then wait for all
resources to be released, which happens when the refcount falls to zero.
Since userspace can keep the refcount incremented by not closing the
relevant file descriptor, the call to unbind may block indefinitely.
This can cause a deadlock during reboot, as evidenced by the following
blocked task observed on my machine:
task:reboot state:D stack:0 pid:2827 ppid:569 flags:0x0000000c

...
The issue can also be observed by opening the card with arecord and
then stopping the process through the shell before unbinding:
# arecord -D hw:UAC2Gadget -f S32_LE -c 2 -r 48000 /dev/null
Recording WAVE '/dev/null' : Signed 32 bit Little Endian, Rate 48000 Hz, Stereo

# echo gadget.0 > /sys/bus/gadget/drivers/configfs-gadget/unbind
(observe that the unbind command never finishes)
Fix the problem by using snd_card_free_when_closed() instead, which will
still disconnect the card as desired, but defer the task of freeing the
resources to the core once userspace closes its file descriptor.

Previously, there was a 100uS delay inserted after issuing an end transfer
command for specific controller revisions. This was due to the fact that
there was a GUCTL2 bit field which enabled synchronous completion of the
end transfer command once the CMDACT bit was cleared in the DEPCMD
register. Since this bit does not exist for all controller revisions and
the current implementation heavily relies on utizling the EndTransfer
command completion interrupt, add the delay back in for uses where the
interrupt on completion bit is not set, and increase the duration to 1ms
for the controller to complete the command.
An issue was seen where the USB request buffer was unmapped while the DWC3
controller was still accessing the TRB. However, it was confirmed that the
end transfer command was successfully submitted. (no end transfer timeout)
In situations, such as dwc3_gadget_soft_disconnect() and
__dwc3_gadget_ep_disable(), the dwc3_remove_request() is utilized, which
will issue the end transfer command, and follow up with
dwc3_gadget_giveback(). At least for the USB ep disable path, it is
required for any pending and started requests to be completed and returned
to the function driver in the same context of the disable call. Without
the GUCTL2 bit, it is not ensured that the end transfer is completed before
the buffers are unmapped.

Commit 130a96d698d7 ("usb: typec: ucsi: acpi: Increase command
completion timeout value") increased the timeout from 5 seconds
to 60 seconds due to issues related to alternate mode discovery.
After the alternate mode discovery switch to polled mode
the timeout was reduced, but instead of being set back to
5 seconds it was reduced to 1 second.
This is causing problems when using a Lenovo ThinkPad X1 yoga gen7
connected over Type-C to a LG 27UL850-W (charging DP over Type-C).
When the monitor is already connected at boot the following error
is logged: "PPM init failed (-110)", /sys/class/typec is empty and
on unplugging the NULL pointer deref fixed earlier in this series
happens.
When the monitor is connected after boot the following error
is logged instead: "GET_CONNECTOR_STATUS failed (-110)".
Setting the timeout back to 5 seconds fixes both cases.

ucsi_init() which runs from a workqueue sets ucsi->connector and
on an error will clear it again.
ucsi->connector gets dereferenced by ucsi_resume(), this checks for
ucsi->connector being NULL in case ucsi_init() has not finished yet;
or in case ucsi_init() has failed.
ucsi_init() setting ucsi->connector and then clearing it again on
an error creates a race where the check in ucsi_resume() may pass,
only to have ucsi->connector free-ed underneath it when ucsi_init()
hits an error.
Fix this race by making ucsi_init() store the connector array in
a local variable and only assign it to ucsi->connector on success.

When ucsi_init() fails, ucsi->connector is NULL, yet in case of
ucsi_acpi we may still get events which cause the ucs_acpi code to call
ucsi_connector_change(), which then derefs the NULL ucsi->connector
pointer.
Fix this by not setting ucsi->ntfy inside ucsi_init() until ucsi_init()
has succeeded, so that ucsi_connector_change() ignores the events
because UCSI_ENABLE_NTFY_CONNECTOR_CHANGE is not set in the ntfy mask.

Now that the same hardware that the r8188eu driver supported is

Also the rtl8xxxu driver supports way more devices, and is a fraction of
the overall size, making this a much better overall solution.

The MT7530 switch from the MT7621 SoC has 2 ports which can be set up as
internal: port 5 and 6. Arınç reports that the GMAC1 attached to port 5
receives corrupted frames, unless port 6 (attached to GMAC0) has been
brought up by the driver. This is true regardless of whether port 5 is
used as a user port or as a CPU port (carrying DSA tags).
Offline debugging (blind for me) which began in the linked thread showed
experimentally that the configuration done by the driver for port 6
contains a step which is needed by port 5 as well - the write to
CORE_GSWPLL_GRP2 (note that I've no idea as to what it does, apart from
the comment "Set core clock into 500Mhz"). Prints put by Arınç show that
the reset value of CORE_GSWPLL_GRP2 is RG_GSWPLL_POSDIV_500M(1) |
RG_GSWPLL_FBKDIV_500M(40) (0x128), both on the MCM MT7530 from the
MT7621 SoC, as well as on the standalone MT7530 from MT7623NI Bananapi
BPI-R2. Apparently, port 5 on the standalone MT7530 can work under both
values of the register, while on the MT7621 SoC it cannot.
The call path that triggers the register write is:
mt753x_phylink_mac_config() for port 6
-> mt753x_pad_setup()
-> mt7530_pad_clk_setup()
so this fully explains the behavior noticed by Arınç, that bringing port
6 up is necessary.
The simplest fix for the problem is to extract the register writes which
are needed for both port 5 and 6 into a common mt7530_pll_setup()
function, which is called at mt7530_setup() time, immediately after
switch reset. We can argue that this mirrors the code layout introduced
in mt7531_setup() by commit 42bc4fafe359 ("net: mt7531: only do PLL once
after the reset"), in that the PLL setup has the exact same positioning,
and further work to consolidate the separate setup() functions is not
hindered.
Testing confirms that:
- the slight reordering of writes to MT7530_P6ECR and to
CORE_GSWPLL_GRP1 / CORE_GSWPLL_GRP2 introduced by this change does not
appear to cause problems for the operation of port 6 on MT7621 and on
MT7623 (where port 5 also always worked)
- packets sent through port 5 are not corrupted anymore, regardless of
whether port 6 is enabled by phylink or not (or even present in the
device tree)
My algorithm for determining the Fixes: tag is as follows. Testing shows
that some logic from mt7530_pad_clk_setup() is needed even for port 5.
Prior to commit ca366d6c889b ("net: dsa: mt7530: Convert to PHYLINK
API"), a call did exist for all phy_is_pseudo_fixed_link() ports - so
port 5 included. That commit replaced it with a temporary "Port 5 is not
supported!" comment, and the following commit 38f790a80560 ("net: dsa:
mt7530: Add support for port 5") replaced that comment with a
configuration procedure in mt7530_setup_port5() which was insufficient
for port 5 to work. I'm laying the blame on the patch that claimed
support for port 5, although one would have also needed the change from
commit c3b8e07909db ("net: dsa: mt7530: setup core clock even in TRGMII
mode") for the write to be performed completely independently from port
6's configuration.
Thanks go to Arınç for describing the problem, for debugging and for
testing.

To last 2 parameters to cfg80211_get_bss() should be of
the enum ieee80211_bss_type resp. enum ieee80211_privacy types,
which WLAN_CAPABILITY_ESS very much is not.
Fix both cfg80211_get_bss() calls in ioctl_cfg80211.c to pass
the right parameters.
Note that the second call was already somewhat fixed by commenting
out WLAN_CAPABILITY_ESS and passing in 0 instead. This was still
not entirely correct though since that would limit returned
BSS-es to ESS type BSS-es with privacy on.

There are 2 issues with the key-store index handling
1. The non WEP key stores can store keys with indexes 0 - BIP_MAX_KEYID,
this means that they should be an array with BIP_MAX_KEYID + 1
entries. But some of the arrays where just BIP_MAX_KEYID entries
big. While one other array was hardcoded to a size of 6 entries,
instead of using the BIP_MAX_KEYID define.
2. The rtw_cfg80211_set_encryption() and wpa_set_encryption() functions
index check where checking that the passed in key-index would fit
inside both the WEP key store (which only has 4 entries) as well as
in the non WEP key stores. This breaks any attempts to set non WEP
keys with index 4 or 5.
Issue 2. specifically breaks wifi connection with some access points
which advertise PMF support. Without this fix connecting to these
access points fails with the following wpa_supplicant messages:
nl80211: kernel reports: key addition failed
wlan0: WPA: Failed to configure IGTK to the driver
wlan0: RSN: Failed to configure IGTK
wlan0: CTRL-EVENT-DISCONNECTED bssid=... reason=1 locally_generated=1
Fix 1. by using the right size for the key-stores. After this 2. can
safely be fixed by checking the right max-index value depending on the
used algorithm, fixing wifi not working with some PMF capable APs.

Remove function _rtl92e_dm_check_ac_dc_power calling a script
/etc/acpi/wireless-rtl-ac-dc-power.sh that is not available. This script
is not part of the kernel and it is not available on the www. The result
is that this function is just dead code.

Use devm_bitmap_zalloc() instead of hand-writing them.
It is less verbose and it improves the semantic.

When mailboxes are used as a transport it is possible to setup the SCMI
transport layer, depending on the underlying channels configuration, to use
one or two mailboxes, associated, respectively, to one or two, distinct,
shared memory areas: any other combination should be treated as invalid.
Add more strict checking of SCMI mailbox transport device node descriptors.

Fix deletion of existing DSCP mappings in the APP table.
Adding and deleting DSCP entries are replicated per-port, since the
mapping table is global for all ports in the chip. Whenever a mapping
for a DSCP value already exists, the old mapping is deleted first.
However, it is only deleted for the specified port. Fix this by calling
sparx5_dcb_ieee_delapp() instead of dcb_ieee_delapp() as it ought to be.
Reproduce:
// Map and remap DSCP value 63
$ dcb app add dev eth0 dscp-prio 63:1
$ dcb app add dev eth0 dscp-prio 63:2
$ dcb app show dev eth0 dscp-prio
dscp-prio 63:2
$ dcb app show dev eth1 dscp-prio
dscp-prio 63:1 63:2 <-- 63:1 should not be there
Fixes: 8dcf69a64118 ("net: microchip: sparx5: add support for offloading dscp table")
