[alsa-devel] [PATCH 20/26] ASoC: SOF: add a flag suspend_ignored for sof stream

[Pierre-Louis Bossart]

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

Add a suspend_ignored flag to snd_sof_pcm_stream that will be used to
decide if the corresponding FW pipeline should be kept active to perform
always on tasks when the system is entering the S0ix state.
