From ca4513fe06c483bf0111c990059d42f97288605d Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Tue, 9 Dec 2008 12:35:52 +0200 Subject: ASoC: TWL4030: Do not alter the Headset output volume on power-up/down There is a separate gain control for the Headset output already. Do not reset the gain to 0 dB at power up. In power-down, there is no need to set the Headset output gain to power-down mode, since if the CODECPDZ is in powered off this setting has no effect.
