In this case, udp_tunnel_nic_register()\nreturning an error is just a failed operation, not a kernel bug.\n\nudp_tunnel_nic_register() can fail due to a memory allocation\nfailure (kzalloc() or udp_tunnel_nic_alloc()).\nThis is a normal runtime error and not a kernel bug.\n\nReplace netdev_WARN() with netdev_warn() accordingly.",
