  55   This function retrieves the user readable name of a driver in the form of a
  56   Unicode string. If the driver specified by This has a user readable name in
  57   the language specified by Language, then a pointer to the driver name is
  58   returned in DriverName, and EFI_SUCCESS is returned. If the driver specified
  59   by This does not support the language specified by Language,
