I think that's a bit much busy work for not much gain. drm_fourcc.h is
even included as the official source of truth of some khr extensions,
making that header stand-alone and useable cross-platform sounds like
a good idea to me. Something like the below is imo perfectly fine:
diff --git a/include/uapi/drm/drm_fourcc.h b/include/uapi/drm/drm_fourcc.h
index ca48ed0e6bc1..0a121b3efb58 100644
--- a/include/uapi/drm/drm_fourcc.h
+++ b/include/uapi/drm/drm_fourcc.h
