Subject: [PATCH] drm/panel: visionox-rm69299: add backlight dependency
Date: Thu, 4 Dec 2025 10:47:26 +0100 [thread overview]
Message-ID: <20251204094734.1031114-1-arnd@kernel.org> (raw)
From: Arnd Bergmann <arnd@arndb.de>
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")
