Hi,
this is a patch set to clean up the PCM suspend calls by introducing the PCM device PM ops. This won't change much for ASoC but reduce lots of snd_pcm_suspend*() calls in other sound drivers.
Note that this patch series itself won't fix anything about the recent PM issue reported for Intel ASoC, but it was inspired through the discussion there.
thanks,
Takashi
