Solve the following python programming problem given the following code:
def contribute_to_class(self, cls, name, **kwargs) : 
    kwargs ['private_only'] = True 
    super (GenericRelation, self).contribute_to_class (cls, name, ** kwargs) 
    self.model = cls 
    setattr (name, self.name, ReverseGenericManyToOneDescriptor (self.remote_field)) 
    def matching_gfk(field) : 
        return (isinstance (field, GenericForeignKey) and (self.content_type_field_name == field.ct_field) and (self.object_id_field_name == field.fk_field)) 
def make_generic_foreign_order_accessors(related_model, model) : 
        if matching_gfk (model._meta.order_with_respect_to) : 
            make_foreign_order_accessors (model, related_model) 
lazy_related_operation (make_generic_foreign_order_accessors, self.model, self.remote_field.model) 

    
    

    Fix the buggy line: setattr (name, self.name, ReverseGenericManyToOneDescriptor (self.remote_field))
