Thanks for picking this up, Matthew.

Unfortunately, it fails to build here:

  CC [M]  drivers/gpu/drm/radeon/radeon_legacy_encoders.o
drivers/gpu/drm/radeon/radeon_legacy_encoders.c: In function ‘radeon_legacy_backlight_init’:
drivers/gpu/drm/radeon/radeon_legacy_encoders.c:358: error: implicit declaration of function ‘pmac_has_backlight_type’
drivers/gpu/drm/radeon/radeon_legacy_encoders.c:403: error: implicit declaration of function ‘machine_is_compatible’
make[1]: *** [drivers/gpu/drm/radeon/radeon_legacy_encoders.o] Error 1
make: *** [_module_drivers/gpu/drm/radeon] Error 2

Am I missing changes from another tree?
