Right now, drivers still have to report this piece of information themselves in their devlink_ops::info_get callback function. In order to factorize code, make devlink_nl_info_fill() add the driver name attribute. Now that the core sets the driver name attribute, drivers are not supposed to call devlink_info_driver_name_put() anymore. Remove devlink_info_driver_name_put() and clean-up all the drivers using this function in their callback.
