Subject: [PATCH] ALSA: sb: Support PCM sync_stop
Git-commit: f9236dd027b85846f2fb7f959cc4baaf165d339f
Patch-mainline: v5.6-rc1
References: jsc#SLE-16518

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