inline lgff_init stub simply allows compilation on systems with CONFIG_LOGITECH_FF disabled. The inline lgff_init should return -ENODEV instead -1 to indicate lack of support when attempting to register an lg_driver on such a system with CONFIG_LOGITECH_FF disabled. Same for inline lg2ff_init and lg3ff_init stub when CONFIG_LOGIRUMBLEPAD2_FF and CONFIG_LOGIG940_FF disabled.
