	169	\r
	170	This function retrieves the user readable name of the controller specified by\r
	171	ControllerHandle and ChildHandle in the form of a Unicode string. If the\r
	172	driver specified by This has a user readable name in the language specified by\r
	173	Language, then a pointer to the controller name is returned in ControllerName,\r
	174	and EFI_SUCCESS is returned. If the driver specified by This is not currently\r
	175	managing the controller specified by ControllerHandle and ChildHandle,\r
	176	then EFI_UNSUPPORTED is returned. If the driver specified by This does not\r
	177	support the language specified by Language, then EFI_UNSUPPORTED is returned.\r
	178	\r

	181	\r
	182	@param[in] ControllerHandle The handle of a controller that the driver\r

	184	specifies the controller whose name is to be\r
	185	returned.\r
	186	\r
	187	@param[in] ChildHandle The handle of the child controller to retrieve\r
	188	the name of. This is an optional parameter that\r
	189	may be NULL. It will be NULL for device\r
	190	drivers. It will also be NULL for a bus drivers\r
	191	that wish to retrieve the name of the bus\r

	198	language of the driver name that the caller is\r
	199	requesting, and it must match one of the\r
	200	languages specified in SupportedLanguages. The\r
	201	number of languages supported by a driver is up\r

	203	RFC 4646 or ISO 639-2 language code format.\r
	204	\r
	205	@param[out] ControllerName A pointer to the Unicode string to return.\r
	206	This Unicode string is the name of the\r
	207	controller specified by ControllerHandle and\r
	208	ChildHandle in the language specified by\r
	209	Language, from the point of view of the driver\r
	210	specified by This.\r
