From 781c7b9615dc1441d6743124086eb3da14bf46e9 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 20 Feb 2015 10:26:25 +0100 Subject: [PATCH] ALSA: hda - Avoid unnecessary power-up at mixer amp changes When the mixer amp is touched by control elements, we don't have to power up always; if the codec was suspended at the time, we can just update the amp cache and it's reflected to the hardware upon resume.
