From 542deb88b0e3696ec9986e804628158169200776 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Thu, 31 Aug 2017 17:30:53 +0100 Subject: [PATCH] net/mlx4_core: fix memory leaks on error exit path The structures hca_param and func_cap are not being kfree'd on an error exit path causing two memory leaks. Fix this by jumping to the existing free memory error exit path. Detected by CoverityScan, CID#1455219, CID#1455224 ("Resource Leak") Fixes: c73c8b1e47ca ("net/mlx4_core: Dynamically allocate structs at mlx4_slave_cap") Signed-off-by: Colin Ian King Acked-by: Tariq Toukan Signed-off-by: David S.
