[PATCH] libata: PIO 0
Ensure the pio_mode is always setup. Don't do any setup on the controller b just ensure the mode reporting is valid to avoid tons of special cases in PATA driver code when mode switching on the fly. Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
