[alsa-devel] [PATCH 1/4] ASoC: wm8350: Don't use locally allocated codec struct

Mark Brown broonie at opensource.wolfsonmicro.com
Mon Apr 30 23:53:12 CEST 2012


The core allocates the live copies, we shouldn't try to duplicate it and
were buggy trying to do so as we were using uninitialised data for the
control data.
