Subject: [PATCH] ALSA: pdaudiocf: Support PCM sync_stop
Git-commit: 2f44742ca1dedf28a832f98199600f945ec90726
Patch-mainline: v5.6-rc1
References: jsc#SLE-16518

The driver invokes snd_pcm_period_elapsed() simply from the threaded
interrupt handler.  Set card->sync_irq for enabling the missing
sync_stop PCM operation.
