ide: add pointer to the current packet command to ide_drive_t
* Add pointer to the current packet command (struct ide_atapi_pc *pc) to ide_drive_t and use it instead of the pointer in struct ide_*_obj. * Use drive->pc in ide_{issue,transfer}_pc() and ide_pc_intr() instead of 'pc' argument. There should be no functional changes caused by this patch. Cc: Borislav Petkov <petkovbb@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
