Subject: [PATCH] ALSA: pcxhr: Support PCM sync_stop
Git-commit: 271213ef4d0d3a3b80d4cf95c5f2bebb5643e666
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.
