When userspace called VIDIOC_STREAMON, then you want to claim any streaming resources needed and validate the video pipeline. Waiting for start_streaming to be called is too late, since that can be postponed until the required minimum of buffers is queued. So add a prepare_streaming op (optional) that can be used for that purpose, and a matching unprepare_streaming op (optional) that can release any claimed resources. The unprepare_streaming op is called when VIDIOC_STREAMOFF is called and q->streaming is 1, or when the filehandle is closed while q->streaming is 1.
