I believe the use of prepare for things like request_firmware etc... is
worth the effort of fixing the known breakage of not having the freezer
while preventing insertion of new devices (mostly USB). In fact, it
won't be such a big issue as the core should/will return an error from
attempting to add the device in that case.
