It is not clear what this lock protects. If the authors wanted to ensure that "dev" does not disappear, that is impossible, given the following code path: mlx4_ib_netdev_event (under RTNL mutex) -> mlx4_ib_scan_netdevs -> mlx4_ib_update_qps Also, the dev_base_lock does not protect dev->dev_addr either. So it serves no purpose here. Remove it.
