From 027bdc85ee74f8f456a47dc53154252ef7d1792f Mon Sep 17 00:00:00 2001 From: Ricardo Neri Date: Fri, 20 Apr 2012 17:17:46 -0500 Subject: [PATCH] OMAPDSS: HDMI: Split audio_enable into audio_enable/disable To improve readability, split the audio_enable HDMI IP operation into two separate functions for enabling and disabling audio. The audio_enable function is also modified to return an error value. While there, update these operations for the OMAP4 IP accordingly.
