The series only includes auto-converted drivers, and the conversion
focused on auto-converting SENSOR_ attributes. While it tried to convert
various instances of the above, that was not the primary focus. I will
likely submit one or more follow-up series to address remaining
SENSOR_... attributes as well as any leftover S_<perms> definitions.
