  61     Language   - A pointer to a three character ISO 639-2 language identifier.
  62                  This is the language of the driver name that that the caller
  63                  is requesting, and it must match one of the languages specified
  64                  in SupportedLanguages.  The number of languages supported by a
  65                  driver is up to the driver writer.
  66     DriverName - A pointer to the Unicode string to return.  This Unicode string
  67                  is the name of the driver specified by This in the language
  68                  specified by Language.

  72                             and the language specified by Language was returned
  73                             in DriverName.
  74     EFI_INVALID_PARAMETER - Language is NULL.
  75     EFI_INVALID_PARAMETER - DriverName is NULL.
  76     EFI_UNSUPPORTED       - The driver specified by This does not support the

 100   Routine Description:
 101     Retrieves a Unicode string that is the user readable name of the controller
 102     that is being managed by an EFI Driver.
 103
 104   Arguments:
 105     This             - A pointer to the EFI_COMPONENT_NAME_PROTOCOL instance.
 106     ControllerHandle - The handle of a controller that the driver specified by
 107                        This is managing.  This handle specifies the controller
 108                        whose name is to be returned.
 109     ChildHandle      - The handle of the child controller to retrieve the name
 110                        of.  This is an optional parameter that may be NULL.  It
 111                        will be NULL for device drivers.  It will also be NULL
 112                        for a bus drivers that wish to retrieve the name of the
 113                        bus controller.  It will not be NULL for a bus driver
 114                        that wishes to retrieve the name of a child controller.
 115     Language         - A pointer to a three character ISO 639-2 language
 116                        identifier.  This is the language of the controller name
 117                        that that the caller is requesting, and it must match one
 118                        of the languages specified in SupportedLanguages.  The
 119                        number of languages supported by a driver is up to the
 120                        driver writer.
 121     ControllerName   - A pointer to the Unicode string to return.  This Unicode
 122                        string is the name of the controller specified by
 123                        ControllerHandle and ChildHandle in the language specified
 124                        by Language from the point of view of the driver specified
 125                        by This.
 126
 127   Returns:
 128     EFI_SUCCESS           - The Unicode string for the user readable name in the
 129                             language specified by Language for the driver
 130                             specified by This was returned in DriverName.
 131     EFI_INVALID_PARAMETER - ControllerHandle is not a valid EFI_HANDLE.
 132     EFI_INVALID_PARAMETER - ChildHandle is not NULL and it is not a valid EFI_HANDLE.
 133     EFI_INVALID_PARAMETER - Language is NULL.
 134     EFI_INVALID_PARAMETER - ControllerName is NULL.
 135     EFI_UNSUPPORTED       - The driver specified by This is not currently managing
 136                             the controller specified by ControllerHandle and
 137                             ChildHandle.
 138     EFI_UNSUPPORTED       - The driver specified by This does not support the
 139                             language specified by Language.
