From 53e5604bbe12fddc549d837190409f25ecb1393a Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 27 Apr 2015 10:36:11 +0200 Subject: ALSA: hda - Fix mute-LED fixed mode MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit commit ee52e56e7b12834476cd0031c5986254ba1b6317 upstream. The mute-LED mode control has the fixed on/off states that are supposed to remain on/off regardless of the master switch. However, this doesn't work actually because the vmaster hook is called in the vmaster code itself. This patch fixes it by calling the hook indirectly after checking the mute LED mode.
