drm/i915: Ignore VBT backlight presence check on Acer C720 (4005U)
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 the Acer C720 (Core i3 4005U CPU), which has a
misconfigured VBT. Apply quirk to ignore the VBT backlight presence check
during backlight setup.
