      Prior to the VRF change the oif was not set in the flow struct, so the
      VRF support should really have only added the vrf_master_ifindex lookup.

      Russell King authored
      Update the docbook comment for __mdiobus_register() to include the new
      module owner argument.  This resolves a warning found by the 0-day
      builder.
