The driver core only creates the sysfs "module" symlink for a built-in driver when its struct device_driver has mod_name set (see module_add_driver()). This driver left mod_name unset, so its built-in form had no such symlink. Set mod_name to KBUILD_MODNAME during driver registration. Built-in drivers now gain the symlink, while loadable modules are unaffected.
