[alsa-devel] [PATCH 01/13] ASoC: core: allow pcms to be registered as nonatomic

[Vinod Koul]

ALSA core with commit 257f8cce5d40 - "ALSA: pcm: Allow nonatomic trigger
operations" allows trigger ops to implemented as nonatomic. For ASoC, we can
specify this in dailinks and is updated while snd_pcm is created
