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
@@ -24,7 +24,11 @@
#ifndef DRM_FOURCC_H
#define DRM_FOURCC_H

+#ifndef DRM_FOURCC_STANDALONE_
+/* include the linux uapi types here */
+#else
#include "drm.h"
+#endif

#if defined(__cplusplus)
extern "C" {


Cheers, Daniel
