Now there is separate entry for PHYLIB [RUST] in MAINTAINERS so it
makes clear that I have to do more maintenance effort. So hopefully,
it's fine by Andrew.
I'll use your workaround in the next version.
I expect that you don't want a commit introducing UD so I squash your
patch with the explanation to the commit log. If you want to merge
your work to the patchset in a different way, please let me know.
Thanks a lot!
