Subject: RDMA/mlx5: fix build error with INFINIBAND_USER_ACCESS=n
Patch-mainline: v5.16-rc1
Git-commit: 97ad8c8c719d0f7fbf3e828be7e99121b4b05b1f
References: jsc#SLE-19249
The mlx5_ib_fs_add_op_fc/mlx5_ib_fs_remove_op_fc functions are only
available when user access is enabled, without that we run into a link
error:
ERROR: modpost: "mlx5_ib_fs_add_op_fc" [drivers/infiniband/hw/mlx5/mlx5_ib.ko] undefined!
ERROR: modpost: "mlx5_ib_fs_remove_op_fc" [drivers/infiniband/hw/mlx5/mlx5_ib.ko] undefined!
Conditionally compiling the newly added code section makes it build,
though this is probably not a correct fix.
Fixes: a29b934ceb4c ("RDMA/mlx5: Add modify_op_stat() support")
