 Drivers can register a regulator by calling :-
 
-struct regulator_dev *regulator_register(struct device *dev,
-	struct regulator_desc *regulator_desc);
+struct regulator_dev *regulator_register(struct regulator_desc *regulator_desc,
+	struct device *dev, struct regulator_init_data *init_data,

 This will register the regulators capabilities and operations to the regulator
 core.
