[alsa-devel] [PATCH 07/26] ASoC: SOF: add flag to snd_sof_pcm_stream for D0i3 compatible stream

From: Keyon Jie <yang.jie at linux.intel.com>

Add flag d0i3_compatible to struct snd_sof_pcm_stream to denote if the
stream can tolerate a transition to the D0i3 substate while opened (thus
seen as 'active' by pm_runtime).
