Do you expect this to be a backport candidate and if so how far back do you think it will go ? To be honest, I am not really convinced that backporting this would be a service to users. The situation I have, where I changed the compiler but kept the old kernel code and old configuration, is going to be fairly rare. I think I should probably therefore disable this driver in the config on stable branches of Linux, at least. Thanks, Ian.
