Subject: IB/mad: Fix memory leak in switch handling in ib_mad_recv_done_handler()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=86dfbecdea733a6e940b958e94a85af45b89a0b9;p=openwrt%2Fstaging%2Fblogic.git

IB/mad: Fix memory leak in switch handling in ib_mad_recv_done_handler()

If agent_send_response() returns an error, we shouldn't do anything
differently than if it succeeds; setting response to NULL just means
that the response buffer gets leaked.
