![]() USB generic driver When preparing capture URBs, we don't need to stop when we cross a period boundary because we now never handle more than one millisecond of data per URB anyway. When handling captured data, use an extra flag to call snd_pcm_period_elapsed() no more than once. This allows us to move the period boundary checking code before the copying of the data which avoids a second locking of the substream's lock. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> |
