No, he doesn't have to do anything at all with his patches. They aren't
the FSF's to define the license for. For ONLY the work he authored or
has the rights of authorship in, he may do whatever he wishes with it.

Even worse, he only has to OFFER to make available the kernel source: a
written offer, good for longer than three years, to provide the source for
no more than the cost of media.
