I have been sent an example of sg_verify giving strange results
in BYTCHK mode. A bus analyzer is showing a properly formed
sense buffer with a sense_key of MISCOMPARE. In lk 3.3.0
scsi_check_sense() is detecting this case and setting
DID_TARGET_ERROR. For a pass-through call originating from
the sg or bsg driver that is unwelcome interference.
Since users of a SCSI command pass-through should be
checking the SCSI status and sense buffer, then commands
issued by the bsg and sg driver (probably st as well)
should not be calling scsi_check_sense() IMO.
