Since the else statement returns, we can simplify this by inverting it:
```
if invalidPasswords != nil {
return errors.New("password blacklist is already loaded")
}
invalidPasswords = make(map[string]bool)
```
Also note we don't need `fmt.Errorf` unless we're using string formatting,
otherwise we can just use `errors.New`.[ Full content available at: https://github.com/apache/trafficcontrol/pull/2852 ] This message was relayed via gitbox.apache.org for [email protected]
