[PATCH] mdio_bus: don't return NULL from mdiobus_scan()

[Sergei Shtylyov]

I've finally noticed that mdiobus_scan() also returns either NULL or error
value on failure.  Return ERR_PTR(-ENODEV) instead of NULL since this is
the  error value  already filtered out by the callers that want to ignore
the  MDIO address scan failure...
