Thanks, as far as I can see you fixed the build failure if the backlight
driver isn't compiled in.
However wouldn't a Kconfig entry still be useful so it turns up under
make menuconfig? For my problem with the miniconfig genereation a simple
"select BACKLIGHT_PCF50633" in the appropriate Kconfig file would work.
This would ensure that it's reconiced as a required option and kept in
generated miniconfig file.
