Revert "ide: skip probe if there are no devices on the port (v2)"
This reverts commit a20b2a44eca52818ef52a94959480b7e6ea2f528. As requested by David Fries. This makes CDROMs which are slave drives on a ribbon without a master disappear and causes other similar kinds of badness. Signed-off-by: David S. Miller <davem@davemloft.net>
