The change to keep things working here (pending the other changes which Russell wants) is to add a dummy resource with a wide enough range of registers defined and make it the parent for all the _IO resouces the PMIC has. This will put all the PMIC _IO resources in a separate tree to ioport_resource which can have the resorces added. If nothing else this seems much more suitable for stable and -rc (the bug has been there since v3.4). -- 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/
