[ Upstream commit dc2f650f7e6857bf384069c1a56b2937a1ee370d ]
netdev_WARN() uses WARN/WARN_ON to print a backtrace along with file and line information. In this case, udp_tunnel_nic_register() returning an error is just a failed operation, not a kernel bug.
udp_tunnel_nic_register() can fail due to a memory allocation failure (kzalloc() or udp_tunnel_nic_alloc()). This is a normal runtime error and not a kernel bug.
Replace netdev_WARN() with netdev_warn() accordingly.
