Add empty static inline function fallbacks if backlight support is not enabled, so that drivers using the backlight don't fail to build. Fixes: In function `simple_panel_ioctl': undefined reference to `of_backlight_find' undefined reference to `backlight_set_brightness_default' undefined reference to `backlight_set_brightness' Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
