I suspect that the building system tries to confine variables to sub-directories, so maybe one solution would be to move it to the main makefile. could you please check if this patch solves the issue? [PATCH] Makefile: move KERNELDOC macro to the main Makefile As kernel-doc script is used not only on Documentation, but also on scripts and drivers/drm Makefiles, move it to the main makefile, as otherwise sub-makefiles may not have it.
