The err = mlxsw_driver->resources_register(mlxsw_core); pointer is a pointer to mlxsw_sp_resources_register(). That function doesn't clean up after itself on failure. Ideally, you'd want a matching mlxsw_driver->resources_unregister as well pointer instead of hard coding devlink_resources_unregister(). The error handling would be easier to review if the gotos told you what the did. Right now they're written in "come from" style so the tell you what happened on the line before. if (!foo) goto allocating_foo_failed; Hopefully if someone fixes mlxsw_sp_resources_register() they'll choose better label names. regards, dan carpenter -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
