I think the logic needs to be the reverse: instead of 'select
BACKLIGHT_CLASS_DEVICE',
this should be 'depends on BACKLIGHT_CLASS_DEVICE', and the same for ACPI_VIDEO.
We may want to add 'default DRM || FB' to BACKLIGHT_CLASS_DEVICE in the
process so we don't lose it for users doing 'make oldconfig' or 'make defconfig'
The rest of the patch looks good to me.
