1b34121d9f ALSA: usb-audio: Skip bSynchAddress endpoint check if it is invalid
The Linux kernel assumes that get_endpoint(alts,0) and
get_endpoint(alts,1) are eachothers feedback endpoints.
To reassure that validity it will test bsynchaddress to comply with that
assumption. But if the bsyncaddress is 0 (invalid), it will flag that as
a wrong assumption and return an error.
Fix: Skip the test if bSynchAddress is 0.
Note: those with a valid bSynchAddress should have a code quirck added.

f7f5301814 ALSA: usb-audio: fix PCM device order
Some cards have alternate setting with non-PCM format as the first
altsetting in the interface descriptors. This confuses userspace, since
alsa-lib uses device 0 by default. So lets parse interfaces in two steps:
 1. Parse altsettings with PCM formats.
 2. Parse altsettings with non-PCM formats.

This fixes at least following cards:
 - Audinst HUD-mx2
 - Audinst HUD-mini

a67060201b ALSA: usb-audio: fix a memory leak bug
In snd_usb_get_audioformat_uac3(), a structure for channel maps 'chmap' is
allocated through kzalloc() before the execution goto 'found_clock'.
However, this structure is not deallocated if the memory allocation for
'pd' fails, leading to a memory leak bug.

To fix the above issue, free 'fp->chmap' before returning NULL.

c2913b140f ASoC: Fixes for v5.3
A relatively large batch of mostly unremarkable fixes here, a couple of
 small core fixes for fairly obscure issues, more comment/email updates
 with no code impact than usual and a bunch of small driver fixes.
 
 The support for new sample rates in the max98373 driver is a fix for the
 fact that the driver declared support for those rates but would in fact
 return an error if these rates were selected.

ASoC: amd: acp3x: use dma address for acp3x dma driver
We shouldn't assume CPU physical address we get from page_to_phys()
is same as DMA address we get from dma_alloc_coherent(). On x86_64,
we won't run into any problem with the assumption when dma_ops is
nommu_dma_ops. However, DMA address is IOVA when IOMMU is enabled.
And it's most likely different from CPU physical address when AMD
IOMMU is not in passthrough mode.

This patch fixes page faults when IOMMU is enabled.

8c57588313 ALSA: hda/intel: stop probe if DMICS are detected on Skylake+ platforms
The legacy HD-Audio driver cannot handle Skylake+ platforms with
digital microphones. For those platforms, the SOF or SST drivers need
to be used.

This patch provides an automatic way of detecting the presence of
DMICs using NHTL information reported by the BIOS. A kernel kconfig
option or a kernel module parameter provide an opt-in means of
stopping the probe. The kernel would then look for an alternate driver
registered for the same PCI ID to probe.

With this capability, distros no longer have to blacklist
snd-hda-intel, but still need to make sure the SOF/SST drivers are
functional by providing the relevant firmware and topology files in
/lib/firmware/intel

The coexistence between SOF and SST drivers and their dynamic
detection is not addressed by this patch, different mechanisms need to
be used, e.g. DMI-based quirks.

Mark switch cases where we are expecting to fall through.

This patch fixes the following warning (Building: m68k):

sound/oss/dmasound/dmasound_atari.c: warning: this statement may fall
through [-Wimplicit-fallthrough=]:  => 1449:24

Notice that, in this particular case, the code comment is
modified in accordance with what GCC is expecting to find.

37151a41df ALSA: pcm: fix lost wakeup event scenarios in snd_pcm_drain
lost wakeup can occur after enabling irq, therefore put task
into interruptible before enabling interrupts,

without this change, task can be put to sleep and snd_pcm_drain
will delay

f474808acb ALSA: aoa: onyx: always initialize register read value
A lot of places in the driver use onyx_read_register() without
checking the return value, and it's been working OK for ~10 years
or so, so probably never fails ... Rather than trying to check the
return value everywhere, which would be relatively intrusive, at
least make sure we don't use an uninitialized value.

Add mixer quirk for the Focusrite Scarlett 6i6, 18i8, and 18i20 Gen 2
audio interfaces. Although the interfaces are USB compliant,
additional input/output level controls and hardware routing/mixing
functionality are available using proprietary USB requests.

74bf71ed79 ALSA: hda: Fix 1-minute detection delay when i915 module is not available
Distribution installation images such as Debian include different sets
of modules which can be downloaded dynamically.  Such images may notably
include the hda sound modules but not the i915 DRM module, even if the
latter was enabled at build time, as reported on
https://bugs.debian.org/931507

In such a case hdac_i915 would be linked in and try to load the i915
module, fail since it is not there, but still wait for a whole minute
before giving up binding with it.

This fixes such as case by only waiting for the binding if the module
was properly loaded (or module support is disabled, in which case i915
is already compiled-in anyway).

2127c01b7f ALSA: i2c: ak4xxx-adda: Fix a possible null pointer dereference in build_adc_controls()
In build_adc_controls(), there is an if statement on line 773 to check
whether ak->adc_info is NULL:
    if (! ak->adc_info ||
        ! ak->adc_info[mixer_ch].switch_name)

When ak->adc_info is NULL, it is used on line 792:
    knew.name = ak->adc_info[mixer_ch].selector_name;

Thus, a possible null-pointer dereference may occur.

To fix this bug, referring to lines 773 and 774, ak->adc_info
and ak->adc_info[mixer_ch].selector_name are checked before being used.

This bug is found by a static analysis tool STCheck written by us.

dd65f7e19c ALSA: hda - Show the fatal CORB/RIRB error more clearly
The last fallback of CORB/RIRB communication error recovery is to turn
on the single command mode, and this last resort usually means that
something is really screwed up.  Instead of a normal dev_err(), show
the error more clearly with dev_WARN() with the caller stack trace.

Also, show the bus-reset fallback also as an error, too.

ASoC: ti: davinci-mcasp: Correct slot_width posed constraint
The slot_width is a property for the bus while the constraint for
SNDRV_PCM_HW_PARAM_SAMPLE_BITS is for the in memory format.

Applying slot_width constraint to sample_bits works most of the time, but
it will blacklist valid formats in some cases.

With slot_width 24 we can support S24_3LE and S24_LE formats as they both
look the same on the bus, but a a 24 constraint on sample_bits would not
allow S24_LE as it is stored in 32bits in memory.

Implement a simple hw_rule function to allow all formats which require less
or equal number of bits on the bus as slot_width (if configured).
