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

Hi Doug,

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

drivers/infiniband/hw/mlx5/main.c: In function 'mlx5_ib_add':
drivers/infiniband/hw/mlx5/main.c:2255:6: error: too few arguments to function 'mlx5_ib_port_link_layer'
  if (mlx5_ib_port_link_layer(&dev->ib_dev) ==
      ^
drivers/infiniband/hw/mlx5/main.c:89:1: note: declared here
 mlx5_ib_port_link_layer(struct ib_device *device, u8 port_num)
 ^

Caused by commit

  ebd61f68e1c7 ("IB/mlx5: Support IB device's callback for getting the link layer")

interacting with commit

  038d2ef87572 ("IB/mlx5: Add flow steering support")

from the net-next tree.

I have added the following merge fix patch:
