	179	Retrieves a Unicode string that is the user readable name of the controller\r

	181	\r
	182	This function retrieves the user readable name of the controller specified by\r
	183	ControllerHandle and ChildHandle in the form of a Unicode string. If the\r
	184	driver specified by This has a user readable name in the language specified by\r
	185	Language, then a pointer to the controller name is returned in ControllerName,\r
	186	and EFI_SUCCESS is returned. If the driver specified by This is not currently\r
	187	managing the controller specified by ControllerHandle and ChildHandle,\r
	188	then EFI_UNSUPPORTED is returned. If the driver specified by This does not\r
	189	support the language specified by Language, then EFI_UNSUPPORTED is returned.\r

	191	@param This A pointer to the EFI_COMPONENT_NAME2_PROTOCOL or\r
	192	EFI_COMPONENT_NAME_PROTOCOL instance.\r
	193	@param ControllerHandle The handle of a controller that the driver\r
	194	specified by This is managing. This handle\r
	195	specifies the controller whose name is to be\r
	196	returned.\r
	197	@param ChildHandle The handle of the child controller to retrieve\r
	198	the name of. This is an optional parameter that\r
	199	may be NULL. It will be NULL for device\r
	200	drivers. It will also be NULL for a bus drivers\r
	201	that wish to retrieve the name of the bus\r
	202	controller. It will not be NULL for a bus\r
	203	driver that wishes to retrieve the name of a\r
	204	child controller.\r
	205	@param Language A pointer to a Null-terminated ASCII string\r
	206	array indicating the language. This is the\r
	207	language of the driver name that the caller is\r
	208	requesting, and it must match one of the\r
	209	languages specified in SupportedLanguages. The\r
	210	number of languages supported by a driver is up\r
	211	to the driver writer. Language is specified in\r
	212	RFC 4646 or ISO 639-2 language code format.\r
	213	@param ControllerName A pointer to the Unicode string to return.\r
	214	This Unicode string is the name of the\r
	215	controller specified by ControllerHandle and\r
	216	ChildHandle in the language specified by\r
	217	Language from the point of view of the driver\r
	218	specified by This.\r
