This innocent change has a significant side-effect on the ARM's multi_v7_defconfig, because FB_BACKLIGHT symbol is no longer selected, what in turn leaves BACKLIGHT_CLASS_DEVICE symbol selected only as a module. The latter disables some backlight related code in the DRM core, because the DRM core is set to be compiled-in in this defconfig. This leaves all DRM display panels without integrated backlight control, even if the needed modules have been properly loaded and probed. Fix this by selecting BACKLIGHT_CLASS_DEVICE to be compiled-in in multi_v7_defconfig.
