[PATCH 0/2] arch: powerpc: Use backlight power constants

[Thomas Zimmermann]

Commit a1cacb8a8e70 ("backlight: Add BACKLIGHT_POWER_ constants for
power states") introduced dedicated constants for backlight power states.
Convert PowerPC code to the new constants.

The new constants replace the fbdev constants. This is part of a larger
effort to make kernel subsystems more independent from fbdev code and
headers.

[PATCH 1/2] arch: powerpc: Use backlight power constants

[Thomas Zimmermann]

Replace FB_BLANK_ constants with their counterparts from the
backlight subsystem. The values are identical, so there's no
change in functionality or semantics.
