Subject: [PATCH] ALSA: wss: Support PCM sync_stop
Git-commit: 959d4c806d386cd28aa74d65db8f0a226defab10
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.
