Subject: [PATCH] ALSA: vx222: Support PCM sync_stop
Git-commit: 59fdf8e96c03261d5b32166a49be9d7daaf7ef73
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.
