Tony: Right now, it's immutable unless you tell me I applied something incorrectly. Once it goes into irqchip/core, it's immutable no matter what you say. ;-) thx, Jason. -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
