Subject: [PATCH] ALSA: sis7019: Support PCM sync_stop
Git-commit: 39b77268c8cdfff171c09c22f7ee8069139d4f20
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.
