Kamal, not sure if you already submitted the patch as I don't follow the
intel-gfx mailing list. If you have you can ignore this comment. 

I know this bug was marked as NEEDINFO-- not sure if that was just a 'no better
option' or if you were actually waiting on info. I've got one of the Dell
XPS13z Sandy Bridge ultrabooks, so if you need me to test anything I can. 

The latest patch: https://bugzilla.kernel.org/attachment.cgi?id=97751

Correctly fixes backlight controls on Sandy Bridge, and does NOT break
backlight on my other test laptop (Asus with a perfectly functional backlight
control). I cannot test on Ivy Bridge as I dont have one laying around.
