Ok, likely the version of PyLint has been updated on our CI and it's throwing errors due to new rules(@kattni - could you confirm this is what occurred?).

Do you have cycles to fix these linter errors and commit to this branch? Otherwise, I can fix and commit to the branch as well.

I'd like to merge this fix in - thank you for finding it - let me know what you want to do and we'll do it.

@brentru I can't get the check failure to load when I click details, so I can't verify the list of failures. This library uses pre-commit meaning the Pylint version is pinned, so Pylint updating out from under you is not possible at this time. I don't know have an answer to why things here would suddenly start failing.

@brentru I don't think I can handle these linter errors..., I need you to handle this (including my fix) and close this PR. Thx :)

I merged main and it got this passing CI.

Changes look good to me. Tested successfully simpletest and wsgiserver test using feather rp2040 and Ethernet featherwing.
