From 8a860c2bcc84a8e4fbcabb928cd97e4c51b17d93 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Tue, 14 Nov 2017 06:20:16 +0000 Subject: openvswitch: Fix return value check in ovs_meter_cmd_features() In case of error, the function ovs_meter_cmd_reply_start() returns ERR_PTR() not NULL. The NULL test in the return value check should be replaced with IS_ERR().
