The previously registered net_devices are then freed by\nmtk_free_dev() while still in NETREG_REGISTERED state, hitting the\nBUG_ON(dev-\u003ereg_state != NETREG_UNREGISTERED).\n\nRoute the register_netdev() failure to err_unreg_netdev so the net_devices\nregistered so far are properly unregistered before being freed.",
