The loop optimizer seems to go astray here, and produces some warnings
that don't seem valid.
Still, the code can be simplified -- just clear the whole array at the
beginning, and fill in whatever values are valid on the platform.

syzkaller reported an invalid access in PCM OSS read, and this seems
to be an overflow of the internal buffer allocated for a plugin.
Since the rate plugin adjusts its transfer size dynamically, the
calculation for the chained plugin might be bigger than the given
buffer size in some extreme cases, which lead to such an buffer
overflow as caught by KASAN.
Fix it by limiting the max transfer size properly by checking against
the destination size in each plugin transfer callback.

There are cases where we fail before we reach soc_new_pcm which would
init the workqueue. When we fail we attempt to flush the queue which
generates warnings from the workqueue subsystem when we have not inited
the queue. Solution is to use a proxy function to get around this issue.

The commit 609f5485344b ("ALSA: hda: hdmi - preserve non-MST PCM
routing for Intel platforms") tried to restore the old behavior wrt
assignment of the PCM slot for Intel platforms, but this didn't do it
right. As found in the later discussion, a positive pipe id on Intel
platforms can be passed for single monitor attachment case.
This patch reverts the previous attempt and applies a simpler
workaround instead. Actually, for Intel platforms, we can handle as
if per_pin->dev_id=0, assign the primary slot at the first try. This
assures the compatible behavior with the previous versions regarding
the slot assignment.

The recent commit in HD-audio stream management for changing the
stripe control seems causing a regression on some platforms. The
stripe control is currently used only by HDMI codec, and applying the
stripe mask unconditionally may lead to scratchy and static noises as
seen on some MacBooks.
For addressing the regression, this patch changes the stream
management code to apply the stripe mask conditionally only when the
codec driver requested.

Commit 5398e94fb753 ("ALSA: hda - Add DP-MST support for NVIDIA codecs")
introduced a slight change of behaviour how non-MST monitors are
assigned to PCMs on Intel platforms.
In the drm_audio_component.h interface, the third parameter
to pin_eld_notify() is pipe number. On Intel platforms, this value
is -1 for MST. On other platforms, a non-zero pipe id is used to
signal MST use.
This difference leads to some subtle differences in hdmi_find_pcm_slot()
with regards to how non-MST monitors are assigned to PCMs.
This patch restores the original behaviour on Intel platforms while
keeping the new allocation policy on other platforms.

We've added the bass speaker support on Acer 8951G by the commit
00066e9733f6 ("Add Acer Aspire Ethos 8951G model quirk"), but it seems
that the GPIO pin was wrongly set: while the commit turns off the bit
to power up the amp, the actual hardware reacts other way round,
i.e. GPIO bit on = amp on.
So this patch fixes the bug, turning on the GPIO bit 0x02 as default.
Since turning on the GPIO bit can be more easily managed with
alc_setup_gpio() call, we simplify the quirk code by integrating the
GPIO setup into the existing alc662_fixup_aspire_ethos_hp() and
dropping the whole ALC669_FIXUP_ACER_ASPIRE_ETHOS_SUBWOOFER quirk.

Fix regression in how intel_haswell_fixup_connect_list()
results are used in hda_read_pin_conn(). Use of
snd_hda_get_raw_connections() in hda_read_pin_conn() bypasses
the cache and thus also bypasses the overridden pin connection
list. On platforms that require the connection list fixup,
mux list will be empty and HDMI playback will fail to -EBUSY
at open.
Fix the regression in hda_read_pinn_conn(). Simplify code
as suggested by Takashi Iwai to remove old
intel_haswell_fixup_connect_list() and copy the cvt_nid list
directly and not use snd_hda_override_conn_list() at all.

max98090_interrupt() and max98090_pll_work() run in 2 different threads.
There are 2 possible races:
Note: M98090_REG_DEVICE_STATUS = 0x01.
Note: ULK == 0, PLL is locked; ULK == 1, PLL is unlocked.
max98090_interrupt max98090_pll_work
----------------------------------------------
schedule max98090_pll_work
restart max98090 codec
receive ULK INT
assert ULK == 0
schedule max98090_pll_work (1).
In the case (1), the PLL is locked but max98090_interrupt unnecessarily
schedules another max98090_pll_work.
max98090_interrupt max98090_pll_work max98090 codec
----------------------------------------------------------------------
ULK = 1
receive ULK INT
read 0x01
ULK = 0 (clear on read)
schedule max98090_pll_work
restart max98090 codec
ULK = 1
receive ULK INT
read 0x01
ULK = 0 (clear on read)
read 0x01
assert ULK == 0 (2).
In the case (2), both max98090_interrupt and max98090_pll_work read
the same clear-on-read register. max98090_pll_work would falsely
thought PLL is locked.
Note: the case (2) race is introduced by the previous commit ("ASoC:
max98090: exit workaround earlier if PLL is locked") to check the status
and exit the loop earlier in max98090_pll_work.
There are 2 possible solution options:
A. turn off ULK interrupt before scheduling max98090_pll_work; and turn
on again before exiting max98090_pll_work.
B. remove the second thread of execution.
Option A cannot fix the case (2) race because it still has 2 threads
access the same clear-on-read register simultaneously. Although we
could suppose the register is volatile and read the status via I2C could
be much slower than the hardware raises the bits.
Option B introduces a maximum 10~12 msec penalty delay in the interrupt
handler. However, it could only punish the jack detection by extra
10~12 msec.
Adopts option B which is the better solution overall.

It was observed Baytrail-based chromebooks could cause continuous PLL
unlocked when using playback stream and capture stream simultaneously.
Specifically, starting a capture stream after started a playback stream.
As a result, the audio data could corrupt or turn completely silent.
As the datasheet suggested, the maximum PLL lock time should be 7 msec.
The workaround resets the codec softly by toggling SHDN off and on if
PLL failed to lock for 10 msec. Notably, there is no suggested hold
time for SHDN off.
On Baytrail-based chromebooks, it would easily happen continuous PLL
unlocked if there is a 10 msec delay between SHDN off and on. Removes
the msleep().

Some usages only call startup and shutdown without setting hw_params
(e.g. arecord --dump-hw-params). If we don't enable clk in startup, it
will cause ref count error because the clk will be disabled in shutdown.
For this reason, we should move enabling clk from hw_params to startup.
In addition, the hw_params is fixed in this driver(48000 rate, 2
channels, S16_LE format) so we don't need to change the clk rate after
the hw_params is set.

loopback_parse_timer_id() uses snd_card_ref(), that can lock on mutex,
also snd_timer_instance_new() uses non-atomic allocation, that can sleep.
So, both functions can not be called from loopback_snd_timer_open()
with cable->lock spinlock locked.
Moreover, most part of loopback_snd_timer_open() function body works
when the opposite stream of the same cable does not yet exist, and
the current stream is not yet completely open and can't be running,
so existing locking of loopback->cable_lock mutex is enough to protect
from conflicts with simultaneous opening or closing.
Locking of cable->lock spinlock is not needed in this case.

The old Nvidia chips have multiple HD-audio codecs on the same
HD-audio controller, and this doesn't work as expected with the current
audio component binding that is implemented under the one-codec-per-
controller assumption; at the probe time, the driver leads to several
kernel WARNING messages.
For the proper support, we may change the pin2port and port2pin to
traverse the codec list per the given pin number, but this needs more
development and testing.
As a quick workaround, instead, this patch drops the binding in the
audio side for these legacy chips since the audio component support in
nouveau graphics driver is still not merged (hence it's basically
unused).

We have a new Dell machine which needs to apply the quirk
ALC255_FIXUP_DELL1_MIC_NO_PRESENCE, try to use the fallback table
to fix it this time. And we could remove all pintbls of alc236
for applying DELL1_MIC_NO_PRESENCE on Dell machines.

Add the documentation about the new PCM sync_stop ops and
card->sync_irq field.

Many PCI and other drivers performs snd_pcm_period_elapsed() simply in
its interrupt handler, so the sync_stop operation is just to call
synchronize_irq(). Instead of putting this call multiple times,
introduce the common card->sync_irq field. When this field is set,
PCM core performs synchronize_irq() for sync-stop operation. Each
driver just needs to copy its local IRQ number to card->sync_irq, and
that's all we need.
