I had a quick look and couldn't see anything obviously wrong, but then
I'm no expert with the hwmon code. I build-tested it, and I'm not likely
to any time soon. I think Andrew added the hwmon code for this PHY
originally.

That makes two of us, good enough! :) Thanks for taking a look.

It would of been nice to Cc: the HWMON maintainer. His input would of
been just as valuable as a PHY Maintainer.

Fair point, I lazy'd out and only checked that everyone get_maintainers
asks for was CCed. Perhaps it'd be worth extending the hwmon's keyword
match to trigger on the structs or the constants if it matters.
Adding hwmon@ to CC just in case.

And you expect me to dig up the actual patch ?

Sorry, I assumed we all have some form of fast lore access built 
into our email setups. Here's the link to your reply and therefore 
the thread:

https://lore.kernel.org/all/20220818165856.GC923105@roeck-us.net/

Speaking of expectations tho, I would expect you to not ask me
rhetorical passive aggressive questions.
