Subject: ALSA: ad1889: Support PCM sync_stop
X-Git-Tag: v5.15~4528^2~255
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=164d0738248ac0befb4ce11ca60a06a41838af47;p=platform%2Fkernel%2Flinux-starfive.git

ALSA: ad1889: 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.
