Backlight for v4.5

Hi Linus,

Some of the patches in this set haven't had as long of a -next soak-test as I normally like. This is due to a combination of me taking a vacation from -rc4 and unusually short -rc releases during the v4.4 cycle.

I'm keen not to let down contributors so I am sending the pull- request out in the full knowledge that a snot-o-gram might well be winging it's way to me in receipt. I have taken due care to thoroughly build test the set as much as possible, but if there are any issues I'll take the time to provide reason and apologise in advance now.

The following changes since commit 1ec218373b8ebda821aec00bb156a9c94fad9cd4:

That makes no sense. The rc cycle for 4.4 was _longer_ than usual, not unusually short. Exactly because I expected people to be off a bit over the holidays. And while I have occasionally been off by a few days for individual rc releases, every single 4.4 rc was on a Sunday afternoon.

I've pulled the tree, but am baffled by your pull request.

For some reason I had it in my head that you usually release -rcs on a fortnightly cycle. You can safely ignore the 'unusually short' part, but the remainder still stands and should make sense. The patches in this set have only had a few days soak test, but I'm hoping my AIAIAI testing will stand and none of the builds will be adversely effected. If they are, let me know and I'll fix posthaste.
