From 3712e0f26c41dcf5e5fbde855a3b792d508102a6 Mon Sep 17 00:00:00 2001 From: Huazhong Tan Date: Tue, 28 May 2019 17:03:02 +0800 Subject: [PATCH] net: hns3: fix a memory leak issue for hclge_map_unmap_ring_to_vf_vector BugLink: https://bugs.launchpad.net/bugs/1863019 [ Upstream commit 49f971bd308571fe466687227130a7082b662d0e ] When hclge_bind_ring_with_vector() fails, hclge_map_unmap_ring_to_vf_vector() returns the error directly, so nobody will free the memory allocated by hclge_get_ring_chain_from_mbx(). So hclge_free_vector_ring_chain() should be called no matter hclge_bind_ring_with_vector() fails or not.
