I have no real-world event or report backing the change, but it is
simple enough and fixes problems that are potentially very hard to
detect/reproduce. Certainly fodder for 4.8 and probably stable as
well (if you care). But no biggie, so personally I don't mind if
you wait until 4.9, but then again I don't depend on the driver...
