Subject: [PATCH] ALSA: ad1889: Support PCM sync_stop
Git-commit: 164d0738248ac0befb4ce11ca60a06a41838af47
Patch-mainline: v5.6-rc1
References: jsc#SLE-16518
The driver invokes snd_pcm_period_elapsed() simply from the interrupt
handler. Set card->sync_irq for enabling the missing sync_stop PCM
operation.
