Assumptions of OF are not limited to probe in this driver. While I would like to see this assumption properly abstracted, the most expedient/immediate fix is probably to add a depends on OF above. -- Darren Intel Open Source Technology Center -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
