If major == 0 this functions will dynamically allocate a major and
return its number.
If major > 0 this function will attempt to reserve a device with the
given major number and will return zero on success.

The name of this device has nothing to do with the name of the device

devices. If your module name has only one type of devices it´s ok to
use e.g. the name of the module here.
