Subject: ALSA: aw2: Support PCM sync_stop
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f8582e001f72bbd279f2559122e12741fda90619;p=linux.git

ALSA: aw2: 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.
