Subject: [PATCH] ALSA: es1968: Support PCM sync_stop
Git-commit: dbb71ab05f39162e7e65dbde36cd60be50a4bd5c
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, as well as removing the superfluous synchronize_irq()
call.
