Correct, this should be removed. The processing of the mpt reply has
been pushed to user-space. On another note, according to the mpi
specification, its says there should always be a reply message frame
returned for every smp passthru. So I thinking this would be the best
way to close out the end of this function. What do you think?
+ if (ioc->sas_mgmt.status & MPT_IOCTL_STATUS_RF_VALID) {
+ SmpPassthroughReply_t *smprep;
+
+ smprep = (SmpPassthroughReply_t *)ioc->sas_mgmt.reply;
+ memcpy(req->sense, smprep, sizeof(*smprep));
+ req->sense_len = sizeof(*smprep);
+ } else
+ printk(KERN_ERR "%s: smp passthru reply failed to be
returned\n", __FUNCTION__);
+ ret = -ENXIO;
+ }
