Subject: [patch net-next 1/8] devlink: call devlink_port_register/unregister() on registered instance
From: Jiri Pirko <jiri@...dia.com>
Change the drivers that use devlink_port_register/unregister() to call
these functions only in case devlink is registered.
Signed-off-by: Jiri Pirko <jiri@...dia.com>
