Subject[PATCH net-next] net/mlx5e: Remove NULL check before dev_{put, hold}
Date
The call netdev_{put, hold} of dev_{put, hold} will check NULL,
so there is no need to check before using dev_{put, hold},
remove it to silence the warnings:

./drivers/net/ethernet/mellanox/mlx5/core/en/tc_tun_encap.c:734:2-9: WARNING: NULL check before dev_{put, hold} functions is not needed.
./drivers/net/ethernet/mellanox/mlx5/core/en/tc_tun_encap.c:769:2-9: WARNING: NULL check before dev_{put, hold} functions is not needed.
