I'm definitely not an expert (and couldn't quickly find a good
reference) here but I was under the impression that in such cases you
can just add a note like "based on 'hyperv_fb' driver" (if really
needed, if you just borrow a few things then it's even superfluous I
believe). Anyway, I was just a bit surprised to see '2012' in a new file
:-)
