hwmon: (lm80) fix checkpatch messages
Browse files Browse the repository at this point in the history 
Fixed all checkpatch messages except
simple_strto* -> kstr*
This will be addressed in a separate patch

Also left one line-too-long message as it was only a
little bit too long and would become less readable

compile-tested: no warnings or errors
