Subject: [PATCH] ALSA: es1688: Support PCM sync_stop
Git-commit: f5ac512085b5c2667f8db5f09ce8b87648e5cce4
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.
