commit 24aeebbf8ea9 ("scsi: ata: libata: Change ata_eh_request_sense() to
not set CHECK_CONDITION") changed the way how SAM_STAT_CHECK_CONDITION is
set. Assignment "scmd->result = SAM_STAT_CHECK_CONDITION;" was replaced by
set_status_byte() which does not clear the scsicmd->result.
By not clearing the scsicmd->result we end up in a state where both
the DID_TIME_OUT host byte and the SAM_STAT_CHECK_CONDITION status
bytes are set.
The DID_TIME_OUT host byte is getting set a part of error handling:
ata_qc_complete()
ata_qc_schedule_eh()
blk_abort_request()
WRITE_ONCE(req->deadline, jiffies);
blk_mq_timeout_work()
blk_mq_check_expired()
blk_mq_rq_timed_out()
req->q->mq_ops->timeout() / scsi_timeout()
set_host_byte(scmd, DID_TIME_OUT);
Having the host byte set to DID_TIME_OUT for a command that didn't timeout
is confusing. Let's bring the old behavior back by setting scmd->result to
SAM_STAT_CHECK_CONDITION.
