drm/i915: Ignore VBT backlight check on Macbook 2, 1
commit c675949ec58ca50d5a3ae3c757892f1560f6e896
Author: Jani Nikula <jani.nikula@intel.com>
Date: Wed Apr 9 11:31:37 2014 +0300
drm/i915: do not setup backlight if not available according to VBT
prevents backlight setup on Macbook 2,1. Apply quirk to ignore the VBT
check so backlight is set up properly.
