Ok. I wonder if it would make sense to also make FB_DEVICE depend on FB instead of FB_CORE then. I don't think there is any actual dependency between the two, but as I understand we want modern distros to use neither FB nor FB_DEVICE, so tying them together with a dependency may be desirable anyway. >>> config FB_BACKLIGHT >>> tristate >>> - depends on FB >>> + depends on FB_CORE >>> select BACKLIGHT_CLASS_DEVICE >> >> Separating this one from FB_CORE would help avoid circular dependencies, >> this one keeps causing issues. >> > > You mean separating from FB or should I keep the existing depends on FB? > > It seems this is only used by fbdev drivers so probably the latter? Right, I meant keeping the dependency on FB. Ideally we'd turn this all into a set of 'depends on' instead of 'select', but that is a completely separate topic. Arnd
