ALSA: isight: adjust for new queueing API
Clemens Ladisch [Fri, 17 Jun 2011 06:18:35 +0000 (08:18 +0200)]
Since commit 13882a82ee16 (optimize iso queueing by setting
wake only after the last packet), drivers are required to call
fw_iso_context_queue_flush() after queueing a batch of packets.
The missing call would have an effect only if the controller
queue underruns, but then the DMA would stop completely.
