      ASoC: Intel: avs: DSP recovery and resume fixes · e9a45c8a
      Mark Brown authored 
      Merge series from Cezary Rojewski <cezary.rojewski@intel.com>:

Two fixes that are result of the recent discussions [1][2].

First adds missing locking around snd_pcm_stop() while the second fix
sets substream state to DISCONNECTED if any suspend/resume related
operation fails so that userspace has means to be aware that something
went wrong during said operation.

      ASoC: soc-dai: Do not call snd_soc_link_be_hw_params_fixup() twice · 3115be55
      Richard Fitzgerald authored 
      For a BE link snd_soc_link_be_hw_params_fixup() is called by
dpcm_be_dai_hw_params() to initialize the params before it passes them
to __soc_pcm_hw_params(). Then __soc_pcm_hw_params() refines params to
match the BE codec and passes that to snd_soc_dai_hw_params().

The second call of snd_soc_link_be_hw_params_fixup() within
snd_soc_dai_hw_params() was overwriting the refined params with the
original BE CPU DAI params. This would then lead to various problems,
for example passing an invalid number of channels to the codec driver
hw_params(), or enabling more AIF widgets on the codec than are actually
mapped by TDM slots.

These errors may not be noticed on a simple 1:1 link between one CPU DAI
and one codec DAI, because most likely they have the same DAI config
(though this is not necessarily true, for example if the CPU end has dummy
TDM slots to achieve a desirable BCLK).

For 1:N mappings there are likely to be multiple codecs using different
subsets of the TDM slots and this overwriting of the refined params
can cause incorrect configuration of each codec on the link.

The erroneous extra call to the BE fixup function() was introduced
by:
commit a655de80 ("ASoC: core: Allow topology to override machine
driver FE DAI link config.")

at that time, the call to the BE fixup was already done by
dpcm_be_dai_hw_params(), which was introduced several years earlier
by:
commit 01d7584c ("ASoC: dpcm: Add Dynamic PCM core operations.")

The erroneous code has changed and moved to a different source file
since the patch that introduced it, so this fix patch won't directly
apply as a fix on top of code older than:
commit 8b4ba1d3 ("ASoC: soc-dai: fix up hw params only if it is
needed")

though it can be applied with some minor adjustment to code before
that patch but after:
commit aa6166c2 ("ASoC: soc-dai: mv soc_dai_hw_params() to soc-dai")

On any tree older than that the code is in soc-pcm.c.

      ASoC: wm_adsp: Allow client to hook into pre_run callback · fe071308
      Richard Fitzgerald authored 
      Some HALO-based codecs need some additional custom setup in the
pre_run stage of cs_dsp. Implement the callback in wm_adsp to call
an optional codec driver callback.
