Subject: [PATCH] ALSA: lx6464es: Support PCM sync_stop
Git-commit: 41094b243e621fb67b81a49bab53f5f7e699f429
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.
