Subject: ALSA: bt87x: Support PCM sync_stop
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d2625a62fe7534c6acb4ca3b668d4d46a98beab8;p=linux.git

ALSA: bt87x: 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, as well as removing the superfluous synchronize_irq()
call.
