From 8b3f2eb038d3098b37715afced1e62bbc72da90f Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Tue, 5 Nov 2019 18:27:40 +0000 Subject: [PATCH] net/mlx5: fix kvfree of uninitialized pointer spec Currently when a call to esw_vport_create_legacy_ingress_acl_group fails the error exit path to label 'out' will cause a kvfree on the uninitialized pointer spec. Fix this by ensuring pointer spec is initialized to NULL to avoid this issue.
