In my opinion it's false warning as there is no requirement to have #address-cells in interrupt provider node. by the way, above commit description says: "The interrupt_provider check is noisy, so turn it off for now." -- Best regards, grygorii _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
