From 50f22fd8ecf9001f2813ed0255a26e95f18bb870 Mon Sep 17 00:00:00 2001 From: Noa Osherovich Date: Thu, 20 Apr 2017 20:53:32 +0300 Subject: [PATCH] IB/mlx5: Set mlx5_query_roce_port's return value to void In case of an error, the properties reported to user are zeroed out, so no need for a return value.
