- Routine Description:
- Retrieves a Unicode string that is the user readable name of the controller

- Arguments:
- This - A pointer to the EFI_COMPONENT_NAME_PROTOCOL instance.
- ControllerHandle - The handle of a controller that the driver specified by

- whose name is to be returned.
- ChildHandle - The handle of the child controller to retrieve the name
- of. This is an optional parameter that may be NULL. It
- will be NULL for device drivers. It will also be NULL
- for a bus drivers that wish to retrieve the name of the
- bus controller. It will not be NULL for a bus driver
- that wishes to retrieve the name of a child controller.
- Language - A pointer to a three character ISO 639-2 language
- identifier. This is the language of the controller name
- that that the caller is requesting, and it must match one
- of the languages specified in SupportedLanguages. The
- number of languages supported by a driver is up to the

- string is the name of the controller specified by
- ControllerHandle and ChildHandle in the language specified
- by Language from the point of view of the driver specified
- by This.
-
- Returns:
- EFI_SUCCESS - The Unicode string for the user readable name in the
- language specified by Language for the driver
- specified by This was returned in DriverName.
- EFI_INVALID_PARAMETER - ControllerHandle is not a valid EFI_HANDLE.
