Random noise could be heard when playing audio to the HDMI output.
This is due to the IEC conversion is invoked in the external loop.
As a result, this additional loop takes up a lot of the processing
cycle.
hdmi_reformat_iec958() process the conversion using an internal loop,
it is safe to move it out from the external loop to avoid unnecessary
processing cycle been spent. Furthermore, ALSA IEC958 plugin works in
32bit format only.

Platform was one of mandatory component on ASoC before,
and audio-graph-card was assuming that CPU and Platform were
same driver.
But it is no longer mandatory on ASoC.
Current ASoC will just ignore if Platform and CPU were same
or doplicated component.
Of course ASoC is supporting Platform, but current
audio-graph-card doesn't support detecting it from DT.
This means current audio-graph-card operation for Platform so far
is 100% useless. This patch removes it.
We can respawn it when we need it.

Currently when the call to usb_urb_ep_type_check fails (returning -EINVAL)
the error return path returns -ENOMEM via the exit label "error". Other
uses of the same error exit label set the err variable to -ENOMEM but this
is not being used. I believe the original intent was for the error exit
path to return the value in err rather than the hard coded -ENOMEM, so
return this rather than the hard coded -ENOMEM.

struct link_info can grow fairly large and may cause the stack frame
size to be exceeded when allocated on the stack. Some architectures
such as 32-bit ARM, RISC-V or PowerPC have small stack frames where
this causes a compiler warning, so allocate these structures on the
heap instead of the stack.

The last two patches in this series fix a longstanding issue that prevented
the ALC3263 codec from using a headset mic. This codec can be found on Dell
systems including the Latitude 13 7350, Venue 11 Pro 7140, and XPS 13 9343.
In fact, there is an ACPI quirk for the XPS 13 9343, which forces it to use
legacy HD Audio just to avoid this issue:
https://lore.kernel.org/alsa-devel/CAPeXnHv07HkvcHrYFmZMr8OTp7U7F=k_k=LPYnUtp89iPn2d2Q@mail.gmail.com/
This may allow that ACPI quirk to be removed. Either way, the other systems
mentioned above do not support this quirk and already use the ASoC driver,
so this fix is necessary for headset mic support on those systems.
Note: there is likely other handling for this codec that only exists in the
HDA driver, but which also belongs in the ASoC driver. Commit 394c97f824fa
("ALSA: hda/realtek - Change EAPD to verb control") describes an issue that
does not seem to be resolved in the ASoC driver, to give an example.
Other patches in this series are not specific to the ALC3263. These patches
set the correct combo jack configuration when headphones are inserted, and
fix a misaligned value set in the DMIC2 Configuration Default register.

The ALC3263 codec on the XPS 13 9343 is also found on the Latitude 13 7350
and Venue 11 Pro 7140. They require the same handling for the combo jack to
work with a headset: GPIO pin 6 must be set.
The HDA driver always sets this pin on the ALC3263, which it distinguishes
by the codec vendor/device ID 0x10ec0288 and PCI subsystem vendor ID 0x1028
(Dell). The ASoC driver does not use PCI, so adapt this check to use DMI to
determine if Dell is the system vendor.

During jack detection, the combo jack is configured for a CTIA headset, and
then for an OMTP headset, while sensing the mic connection. If a mic is not
found in either case, the combo jack should be re-configured for headphones
only. This is consistent with the HDA driver behavior.

controls, i.e. control values that does not change on their own without

This doesn't work for readbacks since the DSP firmware updates the

name matches the prefix used for readbacks to ensure that the control

Pioneer devices are supposed to be working with the implicit feedback
mode, but so far the attempt to apply the implicit feedback caused
issues, hence we explicitly skipped the implicit feedback mode for
them. Recently, Geraldo discovered that the device actually works if
you skip the generic matching of the sync EPs for the capture stream.
That is, we should apply the implicit feedback setup for the playback
like other similar devices, while we need to return 1 from
audioformat_capture_quirk() so that no further matching will be done.
And, later on, Olivia reported later that the fiddling with the
capture quirk alone doesn't suffice for the test with speaker-test
program. This seems to be a similar case like the recently fixed BOSS
devices. Indeed, the problem could be addressed by setting
playback_first flag, which indicates that the playback URBs have to be
sent out at first even in the implicit feedback mode.
This patch implements the application of the implicit feedback to
Pioneer devices as described in the above. The former
skip_pioneer_sync_ep() was dropped, and instead we provide
is_pioneer_implicit_fb() to check the Pioneer devices that need the
implicit feedback. In the audioformat_implicit_fb_quirk(), simply
apply the implicit fb for playback and set chip->playback_first flag
if matching, and in audioformat_capture_quirk()(), it returns 1 for
skipping the generic EP sync handling.

Since uprobes is not supported for thumb, check that the thumb bit is
not set when matching the uprobes instruction hooks.
The Arm UDF instructions used for uprobes triggering
(UPROBE_SWBP_ARM_INSN and UPROBE_SS_ARM_INSN) coincidentally share the
same encoding as a pair of unallocated 32-bit thumb instructions (not
UDF) when the condition code is 0b1111 (0xf). This in effect makes it
possible to trigger the uprobes functionality from thumb, and at that
using two unallocated instructions which are not permanently undefined.

vmwgfx fixes for regressions in 5.12
Here's a set of 3 patches fixing ugly regressions
in the vmwgfx driver. We broke lock initialization
code and ended up using spinlocks before initialization
breaking lockdep.
Also there was a bit of a fallout from drm changes
which made the core validate that unreferenced buffers
have been unpinned. vmwgfx pinning code predates a lot
of the core drm and wasn't written to account for those
semantics. Fortunately changes required to fix it
are not too intrusive.
The changes have been validated by our internal ci.

This does the directory entry name verification for the legacy
"fillonedir" (and compat) interface that goes all the way back to the
dark ages before we had a proper dirent, and the readdir() system call
returned just a single entry at a time.
Nobody should use this interface unless you still have binaries from
1991, but let's do it right.
This came up during discussions about unsafe_copy_to_user() and proper
checking of all the inputs to it, as the networking layer is looking to
use it in a few new places. So let's make sure the _old_ users do it
all right and proper, before we add new ones.
See also commit 8a23eb804ca4 ("Make filldir[64]() verify the directory
entry filename is valid") which did the proper modern interfaces that
people actually use. It had a note:
Note that I didn't bother adding the checks to any legacy interfaces
that nobody uses.
which this now corrects. Note that we really don't care about POSIX and
the presense of '/' in a directory entry, but verify_dirent_name() also
ends up doing the proper name length verification which is what the
input checking discussion was about.
[ Another option would be to remove the support for this particular very
old interface: any binaries that use it are likely a.out binaries, and
they will no longer run anyway since we removed a.out binftm support
in commit eac616557050 ("x86: Deprecate a.out support").
But I'm not sure which came first: getdents() or ELF support, so let's
pretend somebody might still have a working binary that uses the
legacy readdir() case.. ]

"The largest change is for a regression that landed during -rc1 for
block-device read-only handling. Vaibhav found a new use for the
ability (originally introduced by virtio_pmem) to call back to the
platform to flush data, but also found an original bug in that
implementation. Lastly, Arnd cleans up some compile warnings in dax.
This has all appeared in -next with no reported issues.

- Fix a regression of read-only handling in the pmem driver
- Fix a compile warning

Pull CXL memory class fixes from Dan Williams:
"A collection of fixes for the CXL memory class driver introduced in
this release cycle.
The driver was primarily developed on a work-in-progress QEMU
emulation of the interface and we have since found a couple places
where it hid spec compliance bugs in the driver, or had a spec
implementation bug itself.
The biggest change here is replacing a percpu_ref with an rwsem to
cleanup a couple bugs in the error unwind path during ioctl device
init. Lastly there were some minor cleanups to not export the
power-management sysfs-ABI for the ioctl device, use the proper sysfs
helper for emitting values, and prevent subtle bugs as new
administration commands are added to the supported list.
The bulk of it has appeared in -next save for the top commit which was
found today and validated on a fixed-up QEMU model.
Summary:
- Fix support for CXL memory devices with registers offset from the
BAR base.
- Fix the reporting of device capacity.
- Fix the driver commands list definition to be disconnected from the
UAPI command list.
- Replace percpu_ref with rwsem to fix initialization error path.
- Fix leaks in the driver initialization error path.
- Drop the power/ directory from CXL device sysfs.
- Use the recommended sysfs helper for attribute 'show'
implementations"

The CXL Identify Memory Device output payload emits capacity in 256MB
units. The driver is treating the capacity field as bytes. This was
missed because QEMU reports bytes when it should report bytes / 256MB.

When I added support to allow generic netlink multicast groups to be
restricted to subscribers with CAP_NET_ADMIN I was unaware that a
genl_bind implementation already existed in the past.
It was reverted due to ABBA deadlock:
1. ->netlink_bind gets called with the table lock held.
2. genetlink bind callback is invoked, it grabs the genl lock.
But when a new genl subsystem is (un)registered, these two locks are
taken in reverse order.
One solution would be to revert again and add a comment in genl
referring 1e82a62fec613, "genetlink: remove genl_bind").
This would need a second change in mptcp to not expose the raw token
value anymore, e.g. by hashing the token with a secret key so userspace
can still associate subflow events with the correct mptcp connection.
However, Paolo Abeni reminded me to double-check why the netlink table is
locked in the first place.
I can't find one. netlink_bind() is already called without this lock
when userspace joins a group via NETLINK_ADD_MEMBERSHIP setsockopt.
Same holds for the netlink_unbind operation.
Digging through the history, commit f773608026ee1
("netlink: access nlk groups safely in netlink bind and getname")
expanded the lock scope.
commit 3a20773beeeeade ("net: netlink: cap max groups which will be considered in netlink_bind()")
... removed the nlk->ngroups access that the lock scope
extension was all about.
Reduce the lock scope again and always call ->netlink_bind without
the table lock.
The Fixes tag should be vs. the patch mentioned in the link below,
but that one got squash-merged into the patch that came earlier in the
series.
