Subject: [PATCH] ALSA: oxygen: Support PCM sync_stop
Git-commit: bf17d20adea74015628a1db0c658d256697b8d83
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.
