Eliminate anonymous module_init() and module_exit(), which can lead to confusion or ambiguity when reading System.map, crashes/oops/bugs, or an initcall_debug log. Give each of these init and exit functions unique driver-specific names to eliminate the anonymous names. Example 1: (System.map) ffffffff832fc78c t init ffffffff832fc79e t init ffffffff832fc8f8 t init Example 2: (initcall_debug log) calling init+0x0/0x12 @ 1 initcall init+0x0/0x12 returned 0 after 15 usecs calling init+0x0/0x60 @ 1 initcall init+0x0/0x60 returned 0 after 2 usecs calling init+0x0/0x9a @ 1 initcall init+0x0/0x9a returned 0 after 74 usecs Fixes: e126ba97dba9 ("mlx5: Add driver for Mellanox Connect-IB adapters") Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Cc: Eli Cohen <eli@mellanox.com> Cc: Saeed Mahameed <saeedm@nvidia.com> Cc: netdev@vger.kernel.org Cc: Leon Romanovsky <leon@kernel.org> Cc: linux-rdma@vger.kernel.org --- drivers/net/ethernet/mellanox/mlx5/core/main.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-)
