Subject: [PATCH] ALSA: bt87x: Support PCM sync_stop
Git-commit: d2625a62fe7534c6acb4ca3b668d4d46a98beab8
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, as well as removing the superfluous synchronize_irq()
call.
