The previous patch addressed a sparse warning but replaced it with a
compiler warning when CONFIG_MODULES is disabled:
drivers/net/ethernet/mellanox/mlx5/core/ipoib.c:485:13: error: 'mlx5_rdma_netdev_free' defined but not used [-Werror=unused-function]
drivers/net/ethernet/mellanox/mlx5/core/ipoib.c:423:27: error: 'mlx5_rdma_netdev_alloc' defined but not used [-Werror=unused-function]
We should never export 'static' functions, so this makes them global
again but hides them in another #ifdef like the change before.
Fixes: a7082ef066f0 ("mlx5: hide unused functions")

Hi Arnd,
Thanks for the patch, but Stephen and Saeed already sent patch similar to it.

Thanks

That link is for the patch that introduced the warning that I'm fixing here,
it showed up yesterday in linux-next.
Did you misread my patch, or just give the wrong link?

Sorry, I misread you patch, because I prepared patch which add users for
these functions and didn't notice both "static" and EXPORT_SYMBOLS at the same time.
I will send it in a couple of minutes.
