4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Moni Shoua <monis@xxxxxxxxxxxx>
commit bebb2a473a43c8f84a8210687d1cbdde503046d7 upstream.
In function addr_resolve() the namespace is a required input parameter
and not an output. It is passed later for searching the routing table
and device addresses. Also, it shouldn't be copied back to the caller.
Fixes: 565edd1d5555 ('IB/addr: Pass network namespace as a parameter')
