Applied to kbuild/linux.git (kbuild-fixes-unstable), thanks!

[1/1] kbuild: Do not run kernel-doc when building external modules
      https://git.kernel.org/kbuild/c/8e249948

Please look out for regression or issue reports or other follow up
comments, as they may result in the patch/series getting dropped,
reverted or modified (e.g. trailers). Patches applied to the
kbuild-fixes-unstable branch are accepted pending wider testing in
linux-next and any post-commit review; they will generally be moved
to the kbuild-fixes branch in a week if no issues are found.

Best regards,
