there is a way, but there is a catch, it must be applied to the explicit class 
of the current level, not of the current device object, since this might be the 
class of the child class.

so the detailed syntax to call the parent realize() is:

        
DEVICE_CLASS(object_class_get_parent(object_class_by_name(CURRENT_CLASS_TYPE_NAME)))->realize(dev,
 &local_err);
