From 17bf1ad2e80db7c9bdafec9c2da72389247194e9 Mon Sep 17 00:00:00 2001 From: Leon Romanovsky Date: Thu, 17 Aug 2017 15:50:54 +0300 Subject: [PATCH] RDMA/mlx4: Properly annotate link layer variable The rdma_port_get_link_layer() returns enum rdma_link_layer as a return value, hence it is better to store the return value in specially annotated variable and not in int.
