Subject: [PATCH] ALSA: cs46xx: Support PCM sync_stop
Git-commit: 763ae53d2ae40feccc7edbeb0067b7f6978699a5
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.
