Subject: [PATCH net-next V1 9/9] net/mlx4_core: Fix inaccurate return value of mlx4_flow_attach()

From: Eyal Perry <eyalpe@...lanox.com>

Adopt the "info: why not propagate 'ret' from parse_trans_rule()..."
suggestion made by the smatch semantic checker on:
drivers/net/ethernet/mellanox/mlx4/mcg.c:867 mlx4_flow_attach()
