Hi,

Why the cpu_dai->active and codec_dai->active are not used to check if the corresponding shutdown or startup callbacks should be called or not?

This could be useful for DAIs that handle capture and playback streams by avoiding:

- perform 2 cpu_dai or codec_dai startup when opening both streams (playback and Capture) - close a cpu_dai or codec_dai for a stream (example playback) while the 2nd stream (playback) is still running

Thanks,

Selma.
