3.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jack Wang <jinpu.wang@xxxxxxxxxxxxxxxx>
commit c807f64340932e19f0d2ac9b30c8381e1f60663a upstream.
The SRP specification requires:
"Response data shall be provided in any SRP_RSP response that is sent in
response to an SRP_TSK_MGMT request (see 6.7). The information in the
RSP_CODE field (see table 24) shall indicate the completion status of
the task management function."
So fix this to avoid the SRP initiator interprets task management functions
that succeeded as failed.
