Hmm, where was this applied?  I do not see it in:
 * v4.4-rc4
 * linux-next next-20151203 (dcccebc - Add linux-next specific files
for 20151203)

Nor do I see it in any branch in:
 * git://git.kernel.org/pub/scm/linux/kernel/git/lee/backlight
Is this the right git?
By the way this repository has a git tag called "HEAD", which is a bit
annoying since every time I "git remote update" from here, git gets
confused until I manually delete it (git tag -d HEAD).

Thanks,
-Dan
