ide: remove ->data_phase field from ide_hwif_t
* Always use hwif->task->data_phase and remove ->data_phase field from ide_hwif_t. * Remove superfluous REQ_TYPE_ATA_TASKFILE check from ide_pio_datablock() while at it. There should be no functional changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
