  Routine Description:\r
    Retrieves a Unicode string that is the user readable name of the controller\r
    that is being managed by an EFI Driver.\r
\r
  Arguments:\r
    This             - A pointer to the EFI_COMPONENT_NAME_PROTOCOL instance.\r
    ControllerHandle - The handle of a controller that the driver specified by\r
                       This is managing.  This handle specifies the controller\r
                       whose name is to be returned.\r
    ChildHandle      - The handle of the child controller to retrieve the name\r
                       of.  This is an optional parameter that may be NULL.  It\r
                       will be NULL for device drivers.  It will also be NULL\r
                       for a bus drivers that wish to retrieve the name of the\r
                       bus controller.  It will not be NULL for a bus driver\r
                       that wishes to retrieve the name of a child controller.\r
    Language         - A pointer to a three character ISO 639-2 language\r
                       identifier.  This is the language of the controller name\r
                       that that the caller is requesting, and it must match one\r
                       of the languages specified in SupportedLanguages.  The\r
                       number of languages supported by a driver is up to the\r
                       driver writer.\r
    ControllerName   - A pointer to the Unicode string to return.  This Unicode\r
                       string is the name of the controller specified by\r
                       ControllerHandle and ChildHandle in the language specified\r
                       by Language from the point of view of the driver specified\r
                       by This.\r
\r
  Returns:\r
    EFI_SUCCESS           - The Unicode string for the user readable name in the\r
