Subject[PATCH] backlight: use of_find_backlight_by_node stub when backlight class disabled
Date
Drivers may want to search for an optional backlight even when the backlight
class is disabled. In this case the linker would miss the function referenced
in the backlight header.

Therefore use the stub function also when the backlight class is disabled.
