From d2625a62fe7534c6acb4ca3b668d4d46a98beab8 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 10 Dec 2019 07:34:07 +0100 Subject: [PATCH] ALSA: bt87x: 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, as well as removing the superfluous synchronize_irq() call.
