From 66a06b0c5997fd45eb22c18e8343a3d3865fd5a1 Mon Sep 17 00:00:00 2001 From: Ricardo Neri Date: Tue, 6 Nov 2012 00:19:14 -0600 Subject: [PATCH] OMAPDSS: HDMI: Handle panel init error at probe Do not blindly assume that the panel could be initialized. While there, group mutex initialization at a single place.
