ASoC: Fixes for v5.5

A collection of fixes since the merge window, mostly driver specific but
there's a few in the core that clean up fallout from the refactorings
done in the last cycle.

We made the error message for the CORB/RIRB communication clearer by
upgrading to dev_WARN() so that user can notice better.  But this
struck us like a boomerang: now it caught syzbot and reported back as
a fatal issue although it's not really any too serious bug that worth
for stopping the whole system.

OK, OK, let's be softy, downgrade it to the standard dev_err() again.

The commit e38e486d ("ALSA: hda: Modify stream stripe mask only
when needed") tried to address the regression by the unconditional
application of the stripe mask, but this caused yet another
regression for the previously working devices.  Namely, the patch
clears the azx_dev->stripe flag at snd_hdac_stream_clear(), but this
may be called multiple times before restarting the stream, so this
ended up with clearance of the flag for the whole time.

This patch fixes the regression by moving the azx_dev->stripe flag
clearance at the counter-part, the close callback of HDMI codec
driver instead.

CA0132 has the delayed HP jack detection code that is invoked from the
unsol handler, but it does a few weird things: it contains the cancel
of a work inside the work handler, and yet it misses the cancel-sync

The current PCM code doesn't initialize explicitly the buffers
allocated for PCM streams, hence it might leak some uninitialized
kernel data or previous stream contents by mmapping or reading the
buffer before actually starting the stream.

Since this is a common problem, this patch simply adds the clearance
of the buffer data at hw_params callback.  Although this does only
zero-clear no matter which format is used, which doesn't mean the
silence for some formats, but it should be OK because the intention is
just to clear the previous data on the buffer.

On CML boards with the RT5682 headset codec and RT1011 speaker
amplifier, the platform firmware exposes three ACPI HIDs
(10EC5682, 10EC1011 and MX98357A). The last HID is a mistake in
DSDT tables, which causes the wrong machine driver to be loaded.

This patch changes the key used to identify boards and changes the
order of entries in the table to load the correct machine driver.
The order does matter and should not be modified to work-around this
firmware issue.

In normal sound case all DAIs are detected as CPU-Codec.
simple_dai_link_of supports the presence of a platform but it counts
it as a CPU DAI resulting in the creation of an extra link.

Adding a platform property to a link description like:

simple-audio-card,dai-link {
	cpu {
		sound-dai = <&sai1>;
	};
	plat {
		sound-dai = <&dsp>;
	};
	codec {
		sound-dai = <&wm8960>;
	}

will result in the creation of two links:
	* sai1 <-> wm8960
	* dsp  <-> wm8960

which is obviously not what we want. We just want one single link
with:
	* sai1 <-> wm8960 (and platform set to dsp).

snd_soc_add_dai_link() might fail. This situation occurs for
instance in a very specific use case where a PCM device and a
Back End DAI link are given identical names in the topology.
When this happens, soc_new_pcm_runtime() fails and then
snd_soc_add_dai_link() returns -ENOMEM when called from
soc_tplg_fe_link_create(). Because of that, the link will not
get added into the card list, so any attempt to remove it later
ends up in a panic.

Fix that by checking the return status and free the memory in case
of an error.

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.

The commit 609f5485 ("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

Commit 5398e94f ("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.

keeping the new allocation policy on other platforms.

We've added the bass speaker support on Acer 8951G by the commit
00066e97 ("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.

                                               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.

According to the datasheet, PLL lock time typically takes 2 msec and
at most takes 7 msec.

Check the lock status every 1 msec and exit the workaround if PLL is
locked.

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().

The simple-card tries to signal the codec to disable rate constraints,
see commit 2458adb8 ("SoC: simple-card-utils: set 0Hz to sysclk when
shutdown"). This wasn't handled by the codec, instead it would set the
FLL frequency to 0Hz which isn't working. Since we don't have any rate
constraints just ignore this request.

If CONFIG_SPI is n, SND_SOC_RT5677_SPI also is n, building fails:

Link unload now fails for ESAI/SAI DAIs with:

"error: invalid DAI type 6" because DAI type is not

Fix this by correctly handling cases where type is ESAI or SAI.
