I obviously didn't make it clear enough in last review.
If you can't return a value in response to reading a sysfs attribute, the
attribute should not exist. See below for a suggestion on this.

In the SCALE_NONE case you are still creating the sysfs attributes to provide
processed. Just have a variant of this macro that doesn't do this.
That way we don't end up with a sysfs attribute that always results in
an error!
