We probably could.
I'm not so sure.
If we select BACKLIGHT_CLASS_DEVICE, we could end up compiling backlight.c without fbdev, and backlight.c uses fb's funcs.
The funny thing is, there is FB_BACKLIGHT, which seems to be designed to be selectable (and is selected). That one depends on FB, but if I'm not mistaken, that dependency does not do anything if FB_BACKLIGHT is selected.
FB_BACKLIGHT in turn selects both BACKLIGHT_LCD_SUPPORT and BACKLIGHT_CLASS_DEVICE, neither of which seem to be designed to be selectable.
I think that's a bit broken. Anyway, I guess it's better to "depend on" here, to be on the safe side.
