commit 28ab9769117ca944cb6eb537af5599aa436287a4 upstream.
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.
