ASoC: Intel: haswell: Mark FE DAIs as nonatomic (dc155ad5) · Commits · 戴 / test

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. Signed-off-by:
