Subject: [PATCH] ALSA: es18xx: Support PCM sync_stop
Git-commit: 58dad836f98cdba69bb4f0b0a9a19af8e39e9fbf
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.
