From: Arnd Bergmann <[email protected]>
The recently added backlight support breaks when CONFIG_BACKLIGHT_CLASS_DEVICE
is turned off:
arm-linux-gnueabi-ld: drivers/gpu/drm/panel/panel-visionox-rm69299.o: in
function `visionox_rm69299_probe':
panel-visionox-rm69299.c:(.text.visionox_rm69299_probe+0x92): undefined
reference to `devm_backlight_device_register'
arm-linux-gnueabi-ld: (devm_backlight_device_register): Unknown destination
type (ARM/Thumb) in drivers/gpu/drm/panel/panel-visionox-rm69299.o
Add the appropriate Kconfig dependency.
Fixes: 7911d8cab554 ("drm/panel: visionox-rm69299: Add backlight support")
