It would be nice to have this fixed in kerneldoc itself. I'm holding this
patch back for two weeks to see if someone wants to work on kerneldoc.

If not, then I'll take this anyway to fix the noise in our build.

Note that while this header is indeed ignored in the documentation, that
is really more a bug and it would be nice to actually include this header
somewhere in our documentation. So fixing these kerneldoc warnings one way
or another is something that we should do.
