Incase you care. The patch is small. I don't know if you need any kind of signed off/written by etc for something so small. In any case there is no intellectual property in this at all. Feel free to do as you wish with it. However including it in the kernel would make my life easier.
Thanks, I fixed it in sound git tree now.
