ide: remove drive->driveid
* Factor out HDIO_[OBSOLETE,GET]_IDENTITY ioctls handling to ide_get_identity_ioctl(). * Use temporary buffer in ide_get_identity_ioctl() instead of accessing drive->id directly. * Add ide_id_to_hd_driveid() inline to convert raw id into struct hd_driveid format (needed on big-endian). * Use ide_id_to_hd_driveid() in ide_get_identity_ioctl(), cleanup ide_fix_driveid() and switch ide to use use raw id. * Remove no longer needed drive->driveid. This leaves us with 3 users of struct hd_driveid in tree: - arch/um/drivers/ubd_kern.c - drivers/block/xsysace.c - drivers/usb/storage/isd200.c While at it: * Use ata_id_u{32,64}() and ata_id_has_{dma,lba,iordy}() macros. There should be no functional changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
