The idea here is to sit in the same class directory as of hwmon. Devices
registered with this interface will have "dev" under, for example,
/sys/class/hwmon/hwmon0/dev. To do the same inside the driver will be
a bit more involved than a call.

In my opinion other classes should also have similar interfaces.
