  28   This function retrieves the user readable name of a driver in the form of a
  29   Unicode string. If the driver specified by This has a user readable name in
  30   the language specified by Language, then a pointer to the driver name is
  31   returned in DriverName, and EFI_SUCCESS is returned. If the driver specified
  32   by This does not support the language specified by Language,
  33   then EFI_UNSUPPORTED is returned.
