Subject: [PATCH] ALSA: ad1816a: Support PCM sync_stop
Git-commit: 0dbba47eb4e9428d8563278123992243c3c62c3e
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.
