From be1391c7858ffd7c5c1b4f004431cfbffb3e923c Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 10 Dec 2019 07:34:23 +0100 Subject: ALSA: intel8x0: Support PCM sync_stop The driver invokes snd_pcm_period_elapsed() simply from the interrupt handler. Set card->sync_irq for enabling the missing sync_stop PCM operation. It's cleared and reset dynamically at IRQ re-acquiring for the PM resume, too.
