Right away, I can see it's dealing with the documentation for the LAN95xx device tree binding.  Digging deeper, it's just a comment fix.

Given that it's just a documentation adjustment, and a trivial one at that, this definitely *should not* require WorthFuzzing.  It's just a clean-up, making the documentation a little more precise. Done.
