[PATCH 00/12] backlight: Do not include <linux/fb.h> in header file

Remove the final dependencies on fbdev from the backlight subsystem.
This is really just the include of <linux/fb.h> in backlight, but it
has some fallout in other code.

Patches 1 to 11 fix all the implicit includes that come from fb.h
throughout the kernel. It's all trivial, but touches various drivers.
Maintainers are in CC. Patch 12 fixes the backlight header.

With the series applied the backlight subsystem should be free from
fbdev dependencies.
