Subject[PATCH next] drm/i915: fix build error without ACPI
Date
If CONFIG_ACPI=n and CONFIG_BACKLIGHT_CLASS_DEVICE=m, compilation complains
with undefined references:

drivers/gpu/drm/i915/display/intel_panel.o: In function `intel_backlight_device_register':
intel_panel.c:(.text+0x4dd9): undefined reference to `backlight_device_register'
drivers/gpu/drm/i915/display/intel_panel.o: In function `intel_backlight_device_unregister':
intel_panel.c:(.text+0x4e96): undefined reference to `backlight_device_unregister'

This patch select BACKLIGHT_CLASS_DEVICE directly.
