Thank you for pointing it.

Sorry. the order of patch series (and explain) was a little bit wrong.

My point was "snd_soc_dai_ops :: trigger" (which call fsi_stream_push/pop)
and "suspend/resume" (which call fsi_stream_is_working)
might be called in same time.
This patch was preparation of cleanup suspend/resume patch.

Best regards
