Logically with the fixes I've send these errors should have gone. Just a 
pr_info should appear "... not attached to any thermal zone".

If I'm correct, without or with the changes (new thermal OF code + 
fixes), the hwmon message is the same and the hwmon thermal zone is not 
created. So no regression hopefully.

Is it possible to check that?
