Changed pin.function so that it's always read-write, which in turn permits InputDevice to force pin.function to "input" rather than checking that it's not "input" first. This ensures internal state in RPi.GPIO and RPIO reflects the reality of each pin's function (see discussion under the ticket for more detail).
