Subject: [PATCH] ALSA: maestro3: Support PCM sync_stop
Git-commit: a20b8bfe557c794ae3a35c1ca9cb25d3abaf7784
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.
