You need to issue a warning here if someone attempts to change the
previously default value of the now deprecated module param. E.g warn
this is deprecated and point them to mlx5_core

It is handled in the module init function:

static int __init mlx5_ib_init(void)
{
-       return pci_register_driver(&mlx5_ib_driver);
+       if (deprecated_prof_sel != 2)
+               pr_warn("prof_sel is deprecated for mlx5_ib, set it
for mlx5_core\n");
+
+       return mlx5_register_interface(&mlx5_ib_interface);
}
