[alsa-devel] [PATCH 4/4] ASoC: SOF: PM: only suspend to D0I3 when needed

[Pierre-Louis Bossart]

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

We should suspend audio to D3 by default, for the sake of power saving,
change the condition of D0I3 suspending here to that when there is
stream with suspend_ignored specified.
