Subject: [PATCH] ALSA: vxpocket: Support PCM sync_stop
Git-commit: 0ca4cefad185da4b1a5ebf1f03a2ec92b7825551
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.
