Subject: [PATCH] ALSA: riptide: Support PCM sync_stop
Git-commit: 3992f78f349f7f1565b43d244177f3975edb9aa1
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.
