From bcf643c51434e1f7930e3b951a406eb63c4c71f6 Mon Sep 17 00:00:00 2001 From: Weihang Li Date: Thu, 20 Jun 2019 16:52:45 +0800 Subject: [PATCH] net: hns3: add exception handling when enable NIC HW error interrupts If we failed to enable NIC HW error interrupts during client initialization in some cases, we should do exception handling to clear flags and free the resources.
