Subject: [PATCH] ALSA: trident: Support PCM sync_stop
Git-commit: 4a9ff148bd348f7489fcc9d1a1ef3723b6f329be
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.
