Subject: ALSA: au88x0: Support PCM sync_stop
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=662a7441316d584d8bf62004ff55d978004a97ec;p=linux.git

ALSA: au88x0: 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.
