Message

The first three patches of this series cleanup libata-core code in the
area of device configuration (ata_dev_configure() function).
Patch 4 improves ata_read_log_page() handling to avoid unnecessary
warning messages and patch 5 adds an informational message on device
scan to advertize the features supported by a device.

Path 6 adds the new sysfs ahci device attribute ncq_prio_supported to
indicate that a disk supports NCQ priority. Patch 7 does the same for
the mpt3sas driver, adding the sas_ncq_prio_supported device attribute.

  libata: cleanup device sleep capability detection
  libata: cleanup ata_dev_configure()
