The documentation states that:
make W=n
can be used to verify the documentation format. This is true for .c
files but not for headers [1].
Modify the documentation to specify that headers files are not covered
by make W=n and that these need to be checked separately with
scripts/kernel-doc.

The best would obviously be to modify scripts/Makefile.build to also
check headers, but this is easier said than done. Updating the
documentation is the best I can offer.
