From 5f45678173a79661409375ffa8b5c297cb932aad Mon Sep 17 00:00:00 2001 From: Frank Schaefer Date: Thu, 21 Mar 2013 13:51:17 -0300 Subject: [PATCH] [media] bttv: separate GPIO part from function audio_mux() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Move the GPIO part of function audio_mux() to a separate function audio_mux_gpio(). This prepares the code for the next patch which will separate mute and input setting.
