Just be aware that there's a good reason the patch was never marked with a Fixes: tag - that is because no one seems to know exactly which commit broke it, and hence it hasn't been clear which stable kernels it should be backported to. So, it's good that someone has put up this backport request. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTC broadband for 0.8mile line in suburbia: sync at 10.2Mbps down 587kbps up
