ASoC: Intel: bdw-rt5677: Mark FE DAIs as nonatomic

crojewsk-intel · broonie · commit fc5c8729c1ef · 2020-10-05T18:18:42.000+01:00
PCM operations for DAI links connected with DSP platform component involve communication with DSP firmware by IPCs. As IPC protocol may cause thread to sleep while waiting for a response from DSP, propagate that information to ALSA core by marking all FE DAIs as nonatomic.
