Subject: [PATCH v5 3/7] ata: libata-scsi: Honor the D_SENSE bit for CK_COND=1
 and no error

SAT-5 revision 8 specification removed the text about the ANSI INCITS
431-2007 compliance which was requiring SCSI/ATA Translation (SAT) to
return descriptor format sense data for the ATA PASS-THROUGH commands
regardless of the setting of the D_SENSE bit.

Let's honor the D_SENSE bit for ATA PASS-THROUGH commands while
generating the "ATA PASS-THROUGH INFORMATION AVAILABLE" sense data.

SAT-5 revision 7
================

12.2.2.8 Fixed format sense data

Table 212 shows the fields returned in the fixed format sense data
(see SPC-5) for ATA PASS-THROUGH commands. SATLs compliant with ANSI
INCITS 431-2007, SCSI/ATA Translation (SAT) return descriptor format
sense data for the ATA PASS-THROUGH commands regardless of the setting
of the D_SENSE bit.

SAT-5 revision 8
================

12.2.2.8 Fixed format sense data

Table 211 shows the fields returned in the fixed format sense data
(see SPC-5) for ATA PASS-THROUGH commands.
