Subject[PATCH 7/8] hisi_sas: add TMF success check
Date
When a tmf is issued, various response codes can be
returned from the target. For a query tmf the
response may be TMF_RESP_FUNC_COMPLETE or
TMF_RESP_FUNC_SUCC.
Add a condition for TMF_RESP_FUNC_SUCC to
hisi_sas_exec_internal_tmf_task().
This affects query tmf, as the result is success
the returned value was for failure.
