Subject: [PATCH v3 0/3] arch/powerpc: Resolve backlight include dependencies

After cleaning up <linux/fb.h> in commit 11b4eedfc87d ("fbdev: Do
not include <linux/backlight.h> in header"), building with
CONFIG_PMAC_BACKLIGHT=y returns errors about missing declarations.
Patches 1 and 2 resolve the errors. Patch 1 has been reviewed at [1].
Patch 3 removes another dependency between backlight and fbdev code.

Compile tested with ppc6xx_defconfig.

v3:
	* add Fixes tag and fix typos in patch 3
v2:
	* via-pmu-backlight: fix build errors
	* powerpc: resolve dependency between fbdev and backlight
