[PATCH 00/14] get rid of the remaining kernel-doc warnings when building the docs

[Mauro Carvalho Chehab]

As described on its subject, this series finally get rid of all kernel-doc warnings.

With this series applied (plus my last series fixing other warnings), building
the docs is now clean[1] against next-20200909:

At least part of those patches won't apply against docs-next, as they depend
on stuff at linux-next. So, it is preferred if they can be applied via each
sub-maintainer's tree.

I'll rebase those during the next merge window. This way, if some
patches ended being missed, they can be applied by the end of the
merge window.

Hopefully, we can make Kernel 5.10 free of documentation warnings.

[1] with the exception of two latmus warnings that seems to require a patch
      that it was not merged yet.

Regards,
Mauro
