Scot Doyle 3149c916e4 drm/i915: Ignore VBT backlight presence check on Acer C720 (4005U) 
commit dfb3d47b23 upstream.

commit c675949ec5
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.
