From fc2a6cf060d0c6feeb3719bf40088e48c5926e40 Mon Sep 17 00:00:00 2001 From: Keyon Jie Date: Wed, 9 Jan 2019 16:20:51 +0800 Subject: [PATCH] ALSA: hda: Fix a mask wrong issue in snd_hdac_stream_start() To enable SIE(Stream Interrupt Enable) in snd_hdac_stream_start(), we should set both mask and value to be "1 << azx_dev->index" for register update, the mask was 0, here fix it.
