Subject: linux-next: build failure after merge of the bpf-next tree

Hi all,

After merging the bpf-next tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/net/ethernet/mellanox/mlx5/core/en_main.c:1605:5: error: conflicting types for 'mlx5e_open_cq'
 int mlx5e_open_cq(struct mlx5e_channel *c, struct dim_cq_moder moder,
     ^~~~~~~~~~~~~
In file included from drivers/net/ethernet/mellanox/mlx5/core/en_main.c:43:
drivers/net/ethernet/mellanox/mlx5/core/en.h:977:5: note: previous declaration of 'mlx5e_open_cq' was here
 int mlx5e_open_cq(struct mlx5e_channel *c, struct net_dim_cq_moder moder,
     ^~~~~~~~~~~~~

Caused by commit

  8960b38932be ("linux/dim: Rename externally used net_dim members")

from the net-next tree interacting with commit

  db05815b36cb ("net/mlx5e: Add XSK zero-copy support")

I have applied the following merge fix patch.
