The message from DT people is... don't worry about DT node refcounting. Do whatever you want with it, they don't care whether you have correct refcounting or not. The background behind that is that I've tried to fix the refcounting, and even had the coccinelle people generate some stuff to work on this issue, but DT people's attitude towards it is "don't bother". So yes, people may get it wrong, but it seems it's something that DT people want ignored. -- RMK's Patch system: http://www.arm.linux.org.uk/developer/patches/ FTTC broadband for 0.8mile line: currently at 9.6Mbps down 400kbps up according to speedtest.net.
