Hi Takashi,

This is what I tried in the SOF driver:
https://github.com/thesofproject/linux/pull/1513/commits

And it seems to cause the system to hang when I stop the stream and I
have no meaningful logs to pinpoint to the problem. Could you please
have a look at the 4 commits that I have added to your series and let
me know what I could be missing? 

Thanks,
Ranjani
