The inline eisa_driver_register stub simply allows compilation on systems with CONFIG_EISA disabled. the dummy eisa_driver_register does not register an *_eisa_driver at all. The inline eisa_driver_register should return to indicate lack of support when attempting to register an *_eisa_driver on such a system with CONFIG_EISA disabled.
