Subject: ALSA: opti9xx: Support PCM sync_stop
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=16d9fb1deef8cf0c83c86a6538f8522a89676d4c;p=linux.git

ALSA: opti9xx: Support PCM sync_stop

The driver invokes snd_pcm_period_elapsed() simply from the interrupt
handler.  Set card->sync_irq for enabling the missing sync_stop PCM
operation.
