ALSA: hda: fix NULL pointer dereference during suspend

When the ASoC card registration fails and the codec component driver
never probes, the codec device is not initialized and therefore
memory for codec->wcaps is not allocated. This results in a NULL pointer
dereference when the codec driver suspend callback is invoked during
system suspend. Fix this by returning without performing any actions
during codec suspend/resume if the card was not registered successfully.

ALSA: hda/hdmi: Fix keep_power assignment for non-component devices

It's been reported that, when neither nouveau nor Nvidia graphics
driver is used, the screen starts flickering.  And, after comparing
between the working case (stable 4.4.x) and the broken case, it turned
out that the problem comes from the audio component binding.  The
Nvidia and AMD audio binding code clears the bus->keep_power flag
whenever snd_hdac_acomp_init() succeeds.  But this doesn't mean that
the component is actually bound, but it merely indicates that it's
ready for binding.  So, when both nouveau and Nvidia are blacklisted
or not ready, the driver keeps running without the audio component but
also with bus->keep_power = false.  This made the driver runtime PM
kicked in and powering down when unused, which results in flickering
in the graphics side, as it seems.

For fixing the bug, this patch moves the bus->keep_power flag change
into generic_acomp_notifier_set() that is the function called from the
master_bind callback of component ops; i.e. it's guaranteed that the
binding succeeded.

ALSA: hda: Workaround for spurious wakeups on some Intel platforms

We've received a regression report on Intel HD-audio controller that
wakes up immediately after S3 suspend.  The bisection leads to the
commit c4c8dd6ef807 ("ALSA: hda: Skip controller resume if not
needed").  This commit replaces the system-suspend to use
pm_runtime_force_suspend() instead of the direct call of
__azx_runtime_suspend().  However, by some really mysterious reason,
pm_runtime_force_suspend() causes a spurious wakeup (although it calls
the same __azx_runtime_suspend() internally).

As an ugly workaround for now, revert the behavior to call
__azx_runtime_suspend() and __azx_runtime_resume() for those old Intel
platforms that may exhibit such a problem, while keeping the new
standard pm_runtime_force_suspend() and pm_runtime_force_resume()
pair for the remaining chips.

Merge tag 'asoc-fix-v5.8-rc5' of https://git./linux/kernel/git/broonie/sound into for-linus

ASoC: Fixes for v5.8

An awful lot of mostly small fixes here, mainly for x86 based platforms
and the CODEC drivers mainly used on them.  For the most part this is
either minor device specific stuff which seems to come from detailed
testing or robustness against errors which comes from people having done
some fuzzing runs aginst the topology code.

ALSA: info: Drop WARN_ON() from buffer NULL sanity check

snd_info_get_line() has a sanity check of NULL buffer -- both buffer
itself being NULL and buffer->buffer being NULL.  Basically both
checks are valid and necessary, but the problem is that it's with
snd_BUG_ON() macro that triggers WARN_ON().  The latter condition
(NULL buffer->buffer) can be met arbitrarily by user since the buffer
is allocated at the first write, so it means that user can trigger
WARN_ON() at will.

This patch addresses it by simply moving buffer->buffer NULL check out
of snd_BUG_ON() so that spurious WARNING is no longer triggered.

ALSA: usb-audio: Fix race against the error recovery URB submission

USB MIDI driver has an error recovery mechanism to resubmit the URB in
the delayed timer handler, and this may race with the standard start /
stop operations.  Although both start and stop operations themselves
don't race with each other due to the umidi->mutex protection, but
this isn't applied to the timer handler.

For fixing this potential race, the following changes are applied:

- Since the timer handler can't use the mutex, we apply the
  umidi->disc_lock protection at each input stream URB submission;
  this also needs to change the GFP flag to GFP_ATOMIC
- Add a check of the URB refcount and skip if already submitted
- Move the timer cancel call at disconnection to the beginning of the
  procedure; this assures the in-flight timer handler is gone properly
  before killing all pending URBs

ALSA: echoaudio: Address bugs in the interrupt handling

Distorted audio appears occasionally, affecting either playback or
capture and requiring the affected substream to be closed by all
applications and re-opened.

The best way I have found to reproduce the bug is to use dmix in
combination with Chromium, which opens the audio device multiple times
in threads. Anecdotally, the problems appear to have increased with
faster CPUs. I ruled out 32-bit counter wrapping; it often happens
much earlier.

Since applying this patch I have not had problems, where previously
they would occur several times a day.

The patch targets the following issues:

* Check for progress using the counter from the hardware, not after it
  has been truncated to the buffer.

  This is a clean way to address a possible bug where if a whole
  ringbuffer advances between interrupts, it goes unnoticed.

* Move last_period state from chip to pipe

  This more logically belongs as part of pipe, and code is reasier to
  read if it is "counter position last time a period elapsed".

  Now the code has no references to period count. A period is just
  when the regular counter crosses a threshold. This increases
  readability and reduces scope for bugs.

* Treat period notification and buffer advance independently:

  This helps to clarify what is the responsibility of the interrupt
  handler, and what is pcm_pointer().

  Removing shared state between these operations means race conditions
  are fixed without introducing locks. Synchronisation is only around
  the read of pipe->dma_counter. There may be cache line contention
  around "struct audiopipe" but I did not have cause to profile this.

Pay attention to be robust where dma_counter wrapping is not a
multiple of period_size or buffer_size.

This is a revised patch based on feedback from Takashi and Giuliano.

ALSA: echoaudio: Race conditions around "opencount"

Use of atomics does not make these statements robust:

       atomic_inc(&chip->opencount);
       if (atomic_read(&chip->opencount) > 1 && chip->rate_set)
               chip->can_set_rate=0;

and

       if (atomic_read(&chip->opencount)) {
               if (chip->opencount) {
                       changed = -EAGAIN;
               } else {
                       changed = set_digital_mode(chip, dmode);

It would be necessary to atomically increment or decrement the value
and use the returned result. And yet we still need to prevent other
threads making use of "can_set_rate" while we set it.

However in all but one case the atomic is misleading as they are already
running with "mode_mutex" held.

Decisions are made on mode setting are often intrinsically connected
to "opencount" because some operations are not permitted unless
there is sole ownership.

So instead simplify this, and use "mode_mutex" as a lock for all reference
counting and mode setting.

[   25.705750]  esai-Codec: ASoC: no backend playback stream
[   27.923378]  esai-Codec: ASoC: no users playback at close - state

This is root-caused to the introduction of the DAI capability checks
with snd_soc_dai_stream_valid(). Its use in soc-pcm.c makes it a
requirement for all DAIs to report at least a non-zero min_channels
field.

ALSA: pcm: Fix build error on m68k and others

The commit 3ad796cbc36a ("ALSA: pcm: Use SG-buffer only when direct
DMA is available") introduced a check of the DMA type and this caused
a build error on m68k (and possibly some others) due to the lack of
dma_is_direct() definition.  Since the check is needed only for
CONFIG_SND_DMA_SGBUF enablement (i.e. solely x86), use #ifdef instead
of IS_ENABLED() for avoiding such a build error.

ASoC: core: Remove only the registered component in devm functions

The ASoC devm_ functions that register a component
(devm_snd_soc_register_component and devm_snd_dmaengine_pcm_register) will
clean their component by running snd_soc_unregister_component.

snd_soc_unregister_component will then remove all the components for the
device that was used to register the component in the first place.

However, some drivers register several components (such as a DAI and a
dmaengine PCM) on the same device, and if the dmaengine PCM is registered
first, then the DAI will be cleaned up first and
snd_dmaengine_pcm_unregister will be called next.

snd_dmaengine_pcm_unregister will then lookup the dmaengine PCM component
on the device, and if there's one unregister that component and release its
dmaengine channels. That doesn't happen in practice though since the first
call to snd_soc_unregister_component removed all the components, so we
never get the chance to release the dmaengine channels.

In order to fix this, instead of removing all the components for a given
device, we can simply remove the component that was registered in the first
place. We should have the same number of component registration than we
have components, so it should work just fine.

ALSA: hda/hdmi: Add Intel silent stream support

External HDMI receivers have analog circuitry that needs to be powered-on
when exiting standby, and a mechanism to detect PCM v. IEC61937 data.
These two steps take time and up to 2-3 seconds of audio may be muted
when starting playback.

Intel hardware (Haswell and beyond) can keep the link active
with a 'silent stream', so that the receiver does not go through those
two steps when valid audio is transmitted. This mechanism relies
on an setting the channel_id as 0xf, sending info packet and preventing
the codec from going to D3,  which will increase the platform
static power consumption. The info packet assumes a basic 2ch stereo,
and the silent stream is enabled when connecting a monitor.
In case of format changes the detection of PCM v. IEC61937 needs to
be re-run. In this case there is no way to avoid the 2-3s mute.

The silent stream is enabled with a Kconfig option, as well as a kernel
parameter should there be a need to override the build time default.
This approach is used based on the power_save capability as an example,
but in the future, it may be used with a kcontrol,
depending on UCM support for HDaudio legacy.

ALSA: compress: document the compress audio state machine

So we had some discussions of the stream states, so I thought it is a
good idea to document the state transitions, so add it documentation

ALSA: compress: fix partial_drain completion state

On partial_drain completion we should be in SNDRV_PCM_STATE_RUNNING
state, so set that for partially draining streams in
snd_compr_drain_notify() and use a flag for partially draining streams

While at it, add locks for stream state change in
snd_compr_drain_notify() as well.

Fixes: f44f2a5417b2 ("ALSA: compress: fix drain calls blocking other compress functions (v6)")
