The duplicate warning is emitted from Sphinx, not kernel-doc.
This is a bug of Sphinx >=3.1, first reported by Mauro back in September 2020 at:
https://github.com/sphinx-doc/sphinx/issues/8241
It was closed when a local fix was presented. Unfortunately, it was not
merged at the time and a subsequent pull request was opened at:
https://github.com/sphinx-doc/sphinx/pull/8313
It is not merged yet and carries a milestone of Sphinx 7.x.
Looks like we need to wait patiently.
Thanks, Akira
