Does it show like this:

        if ((rq->flags & REQ_SENSE) && uptodate) {
                /*
                 * For REQ_SENSE, "rq->buffer" points to the original failed
                 * request
                 */
                struct request *failed = (struct request *) rq->buffer;
                struct cdrom_info *info = drive->driver_data;
                void *sense = &info->sense_data;

                if (failed && block_pc_request(failed))
                        printk("%s: failed %p len=%d  \n", __FUNCTION__, failed->sense,failed->sense_len);

                if (failed && failed->sense)
                        sense = failed->sense;

In that case, I got:

Sorry I certainly didn't understand you right...
