3.16.82-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Paolo Abeni <pabeni@xxxxxxxxxx> commit 8ffeb03fbba3b599690b361467bfd2373e8c450f upstream. All the callers of ovs_flow_cmd_build_info() already deal with error return code correctly, so we can handle the error condition in a more gracefull way. Still dump a warning to preserve debuggability. v1 -> v2: - clarify the commit message - clean the skb and report the error (DaveM) Fixes: ccb1352e76cf ("net: Add Open vSwitch kernel components.")
