[PATCH 06/14] ASoC: Intel: tgl_max98373: fix a runtime pm issue in multi-thread case

[Pierre-Louis Bossart]

>> When the playback & capture streams are stopped simultaneously, the
>> SOF PCI device will remain pm_runtime active. The root-cause is a race
>> condition with two threads reaching the trigger function at the same
>> time. They see another stream is active so the dapm pin is not
>> disabled, so the codec remains active as well as the parent PCI
>> device.

>> For max98373, the capture stream provides feedback when playback is
>> working and it is unused when playback is stopped. So the dapm pin
>> should be set only when playback is active.

Ah yes, good point. I thought it was a SoundWire-only patch but no it 
also applies to the TDM configuration.

These should be a tag:

Fixes: 94d2d08974746 ('ASoC: Intel: Boards: tgl_max98373: add 
dai_trigger function')

Do you want me to resend with the tag, or can you apply it directly?
