From 6607e024014e4920e8d3e43bcfeec0436d43d980 Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Mon, 14 May 2012 12:03:34 +0100 Subject: [PATCH] gma500: Fix crash on D2700MUD and various other boards The recent changes led to the lid timer code being run on various devices. It does no harm on most but isn't needed. It also calls unconditionally into the Poulsbo backlight code which goes bang on Cedartrail.
