For the bug fix I needed to add a line setting data->valid to false
and was reluctant to assign 0 instead as it would be adding more wrong
(type-wise) code. But since you say that's the way to go, sure, will
do.

Regarding the cleanup, I see hwmon has many examples of "char valid"
and so it might make sense to do them all at once. What would be the
procedure here, is that a desired change at all and if yes, how to
approach doing it?
