From 5110bc701b4aa839f461aa5a1a6259bf91b07036 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 10 Dec 2019 07:34:01 +0100 Subject: [PATCH] ALSA: ali5451: 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.
