Merge tag 'ata-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dlemoal/libata

Pull ATA updates from Damien Le Moal:

 - Small cleanup of the pata_octeon driver to drop a useless platform
   callback (Uwe)

 - Simplify ata_scsi_cmd_error_handler() code using the fact that
   ap->ops->error_handler is NULL most of the time (Wenchao)

 - Several patches improving libata error handling. This is in
   preparation for supporting the command duration limits (CDL) feature.
   The changes allow handling corner cases of ATA NCQ errors which do
   not happen with regular drives but will be triggered with CDL drives
   (Niklas)

 - Simplify the qc_fill_rtf operation (me)

 - Improve SCSI command translation for REPORT_SUPPORTED_OPERATION_CODES
   command (me)

 - Cleanup of libata FUA handling.

   This falls short of enabling FUA for ATA drives that support it by
   default as there were concerns that old drives would break. The
   series however fixes several issues with the FUA support to ensure
   that FUA is reported as being supported only for drives that can
   handle all possible write cases (NCQ and non-NCQ). A check in the
   block layer is also added to ensure that we never see read FUA
   commands (current behavior) (me)

 - Several patches to move the old PARIDE (parallel port IDE) driver to
   libata as pata_parport. Given that this driver also needs protocol
   modules, the driver code resides in its own pata_parport directoy
   under drivers/ata (Ondrej)
