+ Language, then a pointer to the controller name is returned in ControllerName,\r
+ and EFI_SUCCESS is returned. If the driver specified by This is not currently\r

+ @param ControllerHandle[in] The handle of a controller that the driver\r
+ specified by This is managing. This handle\r
+ specifies the controller whose name is to be\r
+ returned.\r
+\r
+ @param ChildHandle[in] The handle of the child controller to retrieve\r
+ the name of. This is an optional parameter that\r
+ may be NULL. It will be NULL for device\r

+ to the driver writer. Language is specified in\r
+ RFC 4646 or ISO 639-2 language code format.\r

+ controller specified by ControllerHandle and\r
+ ChildHandle in the language specified by\r
+ Language from the point of view of the driver\r
+ specified by This.\r
