nit-pick: what does this 'Active' comment try to say? the stream_id 
seems to be used for RUN/EOS/CLOSE operations.

In the V1 review we discussed this

May be not!

Plan is that the users of these apis will send flags directly instead of 
boiler plating this!

This change should go as part of next patch("[PATCH 04/11] ASoC: q6asm: 
use flags directly from asm-dai") which would make it much clear!
"

doesn't look like there was a change here?
