[PATCH] uml: make hw_controller_type->release exist only for archs needing it
With Chris Wedgwood <cw@f00f.org> As suggested by Chris, we can make the "just added" method ->release conditional to UML only (better: to archs requesting it, i.e. only UML currently), so that other archs don't get this unneeded crud, and if UML won't need it any more we can kill this.
