The story here is that I took a patch originally developed by Juri and fixed and I heavily modified it. Since the current patch is very different from the original one, Juri suggested I should by the "From:" author, and I simply added his Signed-off-by to acknowledge that he was the author of the original patch. If Juri is ok with your change, I agree with it. Thanks, Luca
