      powerpc: Fix vio_bus_probe oops on probe error · cd5aeb9f
      Brian King authored
      When CMO is enabled and booted on a non CMO system and the VIO
      device's probe function fails, an oops can result since
      vio_cmo_bus_remove is called when it should not.  This fixes it by
      avoiding the vio_cmo_bus_remove call on platforms that don't implement
      CMO.
