Subject: [PATCH] ALSA: fm801: Support PCM sync_stop
Git-commit: e41dbd20383d0dda8813ef6186b142be4de0ddb6
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.
