From: Randy Dunlap <rdunlap@infradead.org>
Fix build errors when INFINIBAND_USER_ACCESS=m and MLX5_INFINIBAND=y. The build error occurs when the mlx5 driver code attempts to use USER_ACCESS interfaces, which are built as a loadable module.
Fixes these build errors:
drivers/infiniband/hw/mlx5/main.o: In function `populate_specs_root': ../drivers/infiniband/hw/mlx5/main.c:4982: undefined reference to `uverbs_default_get_objects' ../drivers/infiniband/hw/mlx5/main.c:4994: undefined reference to `uverbs_alloc_spec_tree' drivers/infiniband/hw/mlx5/main.o: In function `depopulate_specs_root': ../drivers/infiniband/hw/mlx5/main.c:5001: undefined reference to `uverbs_free_spec_tree'
Build-tested with multiple config combinations.
