I guess it's obvious, but should be stated (I'll update the changelog): Also note that this prevents the CORE powerdomain from hitting retention (or off), and thus prevents full-chip retention/off whenever USB devices are attatched, so this should not be considered as a real fix, but a workaround that at least prevents driver failure.
