linux-next: build warning after merge of the net tree

[Stephen Rothwell]

Hi all,

After merging the net tree, today's linux-next build (x86_64 allmodconfig)
produced this warning:

drivers/net/ethernet/mellanox/mlx5/core/en_ethtool.c: In function 
'mlx5e_set_channels':
drivers/net/ethernet/mellanox/mlx5/core/en_ethtool.c:546:6: warning: unused 
variable 'ncv' [-Wunused-variable]
  int ncv = mlx5e_get_max_num_channels(priv->mdev);
      ^

Introduced by commit

  639e9e94160e ("net/mlx5e: Remove unnecessary checks when setting num 
channels")

which removed the last reference to 'ncv'.
