When a USB-audio interface gets runtime-suspended via auto-pm feature,
the driver suspends all functionality and increment
chip->num_suspended_intf.  Later on, when the system gets suspended to
S3, the driver increments chip->num_suspended_intf again, skips the
device changes, and sets the card power state to
SNDRV_CTL_POWER_D3hot.  In return, when the system gets resumed from
S3, the resume callback decrements chip->num_suspended_intf.  Since
this refcount is still not zero (it's been runtime-suspended), the
whole resume is skipped.  But there is a small pitfall here.

The problem is that the driver doesn't restore the card power state
after this resume call, leaving it as SNDRV_CTL_POWER_D3hot.  So,
even after the system resume finishes, the card instance still appears
as if it were system-suspended, and this confuses many ioctl accesses
that are blocked unexpectedly.

In details, we have two issues behind the scene: one is that the card
power state is changed only when the refcount becomes zero, and
another is that the prior auto-suspend check is kept in a boolean
flag.  Although the latter problem is almost negligible since the
auto-pm feature is imposed only on the primary interface, but this can
be a potential problem on the devices with multiple interfaces.

This patch addresses those issues by the following:

- Replace chip->autosuspended boolean flag with chip->system_suspend
  counter

- At the first system-suspend, chip->num_suspended_intf is recorded to
  chip->system_suspend

- At system-resume, the card power state is restored when the
  chip->num_suspended_intf refcount reaches to chip->system_suspend,
  i.e. the state returns to the auto-suspended

Also, the patch fixes yet another hidden problem by the code
refactoring along with the fixes above: namely, when some resume
procedure failed, the driver left chip->num_suspended_intf that was
already decreased, and it might lead to the refcount unbalance.
In the new code, the refcount decrement is done after the whole resume
procedure, and the problem is avoided as well.

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

ASoC: Updates for v5.8

This has been another very active release with a bunch of new drivers,
lots of fixes everywhere and continued core improvements from
Morimoto-san:

 - Lots of core cleanups and refactorings from Morimoto-san, factoring
   out common operations and making the card abstraction more solid.
 - Continued work on cleaning up and improving the Intel drivers, along
   with some new platform support for them.
 - Fixes to make the Marvell SSPA driver work upstream.
 - Support for AMD Renoir ACP, Dialog DA7212, Freescale EASRC and
   i.MX8M, Intel Elkhard Lake, Maxim MAX98390, Nuvoton NAU8812 and
   NAU8814 and Realtek RT1016.

Fixes the following kCFI crash seen on db845c, caused
by the function prototypes not matching the callback
function prototype.

We already have bit field to control snd_soc_card.
Let's add "probed" field on it instead of local variable.

One note here is that soc_cleanup_card_resources()
will be called as (A) formal cleanup or as (B) error handling,
thus, it needs to distinguish these.

In (A) case, card will have "instantiated" flag if all probe
callback functions were called without error.
Thus, snd_soc_unbind_card() is using it to judging card was probed.
But this this patch removes it, because it is no longer needed.

Merge series "Kconfig updates for DMIC and SOF HDMI support" from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:

This series provides the following updates to the Intel machine driver
Kconfig:

1. The first patch adds the explicit dependency on GPIOLIB when
SND_SOC_DMIC is selected.

2. SND_SOC_SOF_HDA_AUDIO_CODEC is required for using the legacy
HDA codec driver for HDMI support in SOF. The last 3 three patches
make the required changes to account for this.

changes since v1:
first patch for DMIC was merged already
rebase for HDMI on top of Arnd's RT5682 changes.

Add support for using generic codec driver with SOF. Generic driver
is used if:
 - snd_sof_intel_hda_common.hda_model="generic" is set, or
 - fallback if no other codec driver is found

The implementation is aligned with snd-hda-intel driver, and fixes audio
support for systems like Acer Swift 3 SF314-57G, on which this issue was
originally reported.

With the allmodconfig option, CONFIG_SND_SOC_SOF_BAYTRAIL is disabled
due to mutual exclusion with the legacy driver. This generates
'defined by not used' warnings.

suspend/resume/remove are only supported for Baytrail for now, so move
the code under the CONFIG_SND_SOC_SOF_BAYTRAIL checks.

FE state is SND_SOC_DPCM_STATE_PREPARE now, BE1 is
used by FE.

Later when new BE2 is added to FE by mixer update,
it will call dpcm_run_update_startup() to update
BE2's state, but unfortunately BE2 .prepare() meets
error, it will disconnect all non started BE.

This make BE1 dai skip .hw_free() and .shutdown(),
and the BE1 users will never decrease to zero.

Recent changes result in multiple dmesg traces such as:

[ 14.410435] Audio Port: ASoC: error at snd_soc_link_startup on Audio
Port: 1

[ 14.410446] sst-mfld-platform sst-mfld-platform: ASoC: error at
snd_soc_dai_startup on media-cpu-dai: 1

These messages are not really errors, when dai and dai-link callbacks
return the value of e.g. snd_pcm_hw_constraint_single() the result is
"Positive if the value is changed, zero if it's not changed, or a
negative error code"

Add a simple test to skip the checks for positive returned values

This small series is to optimize the header logging during the topology
parsing. This is verified work fine on both SOF and SST drivers.

Change History:
v3:
- Remove using the separated soc_pass_load() function and merge it to the
  soc_tplg_load_header() body.
- Add more Tested-by tags.

v2:
- Change the internal used array to be 'static' to fix the issue
  reported by: kbuild test robot <lkp@intel.com>
- Add testing coverage including Intel SST driver also.

v1:
- Initial version.

Keyon Jie (2):
  ASoC: topology: refine and log the header in the correct pass
  ASoC: topology: remove the redundant pass checks
