From b2a232d21f301d600b02c6f9ccbc9f977331bb39 Mon Sep 17 00:00:00 2001 From: Leon Romanovsky Date: Sun, 28 Aug 2016 10:58:35 +0300 Subject: [PATCH] IB/mlx5: Simplify code by removing return variable Return variable was set in a line before the actual return was called in begin_wqe function. This patch removes such variable and simplifies the code.
