Demoting all headers, even if they are conformant, it not the way to
go.  Some contributors/maintainers prefer to keep the kernel-doc
(pretty colours, automated checking [a la, this patch!] and the-like)
formatting, even if they are not directly referenced from
/Documentation.

For now, so long as the build is happy, I am happy.

If you wish to make the build unhappy about this, you should take up
the argument to encompass `scripts/find-unused-docs.sh` into it.
