Apparently drivers need to check all this stuff themselves, which for most things makes sense I guess. And for everything else we luck out, because modern distros stopped supporting any other fbdev drivers than drm ones and I really don't want to argue anymore about who needs to check stuff. Therefore fixing all this just for drm fbdev emulation is good enough. Note that var->active is not set or validated. This is just control flow for fbmem.c and needs to be validated in there as needed.
