Subject: ALSA: cmipci: Support PCM sync_stop
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=3663984e07a4806c891db66c1ac4fed5c36d38f2;p=openwrt%2Fstaging%2Fblogic.git

ALSA: cmipci: 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.
