Why doesn't the tool understand header recursion? drm_mode.h needs to
include drm.h but the rest already include drm.h.

Including drm.h includes linux/types.h if defined(__linux__)

So really I've said this a few times now, its the stupid tool that is
broken for most of these, fix the tool and I'll fix drm_mode.h
