This leads to memory leak because the release\ntiming has already passed. This may also lead to a kernel panic\nas below because of the leaked notifier callback:\n\nCall trace:\n  0xffffa20fccc04978 (P)\n  raw_notifier_call_chain+0x20/0x38\n  call_netdevice_notifiers_info+0x60/0xb8\n  netdev_lower_state_changed+0x4c/0xb8\n\nAs Sashiko suggested, the teardown order of bonding resources should\nbe inverted to make sure the resources are released when the driver\nis removed."
