This patch seems to be the above commit and

commit 1ffff60320879830e469e26062c18f75236822ba

    drm/i915: add quirk to invert brightness on eMachines G725

squashed together. There's a separate bug for that too:
https://bugs.freedesktop.org/show_bug.cgi?id=59628

I think both are okay for stable, but by the stable rules you should
probably split this up, with the appropriate upstream references in
both. Or do whatever the stable team tells you to do. ;)

BR,
Jani.
