Please pull this i915 quirk patch to fix the recent Dell XPS 13 brightness
control regression:

    BugLink: https://bugzilla.kernel.org/show_bug.cgi?id=47941
    BugLink: https://bugs.launchpad.net/bugs/1163720
    BugLink: https://bugs.launchpad.net/bugs/1162026

This fix only affects Dell XPS 13 models (Sandy Bridge and Ivy Bridge).

I have posted this patch to the bugzilla bug (linked above, comment #69), and
will submit it formally upstream pending reaction from upstream users and the
i915 maintainers there.  Since LP: #1163720 is a regression in Raring, I would
like to have it applied as SAUCE in the interim.

Thanks,

 -Kamal
