[GIT PULL] Backlight updates

[Richard Purdie <rpurdie@rpsys.net>]

Hi Linus,

Could you please pull from:
git://git.o-hand.com/linux-rpurdie-backlight for-linus

to receive some backlight updates to address a couple of regressions. 

The fixes have been confirmed by the reporters. The regressions are
being tracked by Adrian.

Thanks,

Richard
