[alsa-devel] [PATCH] ASoC: soc-pcm: BE dai needs prepare when pause release after resume

[libin.yang at intel.com]

From: Libin Yang <libin.yang at intel.com>

If playback/capture is paused and system enters S3, after system returns
from suspend, BE dai needs to call prepare() callback when playback/capture
is released from pause.
