From 83720eef264bbfb6fa94b3eeb2671ffd0bd2dde7 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 10 Dec 2019 07:34:16 +0100 Subject: [PATCH] ALSA: ens137x: 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.
