ata: libata-scsi: Do not set the INFORMATION field twice for ATA PT
For ATA PASS-THROUGH + fixed format sense data + NCQ autosense
the INFORMATION sense data field is being written twice:
- 1st write: (redundant)
scsi_set_sense_information() sets the INFORMATION field to ATA LBA.
This is incorrect for ATA PASS-THROUGH.
- 2nd write: (correct)
ata_scsi_set_passthru_sense_fields() sets the INFORMATION field
to ATA ERROR/STATUS/DEVICE/COUNT(7:0) as per SAT spec.
There is no user-visible issue because second write overwrites
the incorrect data from the first write.
This patch eliminates the reduntant write by moving the INFORMATION
sense data field population logic to ata_scsi_qc_complete().
