Merge patch series "NCQ Priority sysfs sttributes for libsas"
Igor Pylypiv <ipylypiv@google.com> says:
This patch series adds ncq_prio_supported and ncq_prio_enable sysfs
attributes for libsas managed SATA devices. Existing libata sysfs
attributes cannot be used directly because the ata_port location is
different for libsas.
