I'll not make you happy, but in the first patch [v5 01/12], you
accidentally introducing the wifi node, and here you removing part of it..
You need to rebase again :(
I recommend doing `git rebase -i next-202512XX` and go patch by patch
and check it really do what it's meant to be..
rebasing is sometimes pain when larger changes are done.
