So this is a logic change AFAICS, and I have no idea what machines we'd need to test on to check it. So I think an of_node_get(master) would be safer and also fix the refcounting. cheers -- 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
