From f6c1f2d5e5d50366910fd687e88d07ebaabe00ab Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Sun, 8 May 2011 09:24:42 -0700 Subject: [PATCH] ASoC: SSM2602: Do not power the codec up in probe It is not required to have the codec powered at this stage and DAPM will power the ADC and DAC down again after probe has run anyway. Thus we avoid some unnecessary writes by this change.
