Running "make htmldocs" generates several lines of this warning:

Documentation/sphinx/kerneldoc.py:141: RemovedInSphinx80Warning: Sphinx 8 will drop support for representing paths as strings. Use "pathlib.Path" or "os.fspath" instead.
  doc = (env.srcdir + "/" + env.docname + ":" + str(self.lineno))

Making "doc" an fspath type and creating a new variable with the
appended colon and lineno fixes this warning.

This patch should be sent to the linux-doc@vger.kernel.org mailing list,
with the Documentation maintainer copied on the patch.

We also have this similar patch to consider:
  https://lore.kernel.org/linux-doc/20230910040811.53046-1-erer1243@gmail.com/

Thanks.
