Fireworks and Dice drivers try to touch instances of FireWire unit after sound card object is released, while references to the unit is decremented in .remove(). When unplugging during streaming, sound card object is released after .remove(), thus Fireworks and Dice drivers causes GPF or Null-pointer-dereferencing to application processes because an instance of FireWire unit was already released. This commit adds reference-counting for FireWire unit in drivers to allow them to touch an instance of FireWire unit after .remove(). In most case, any operations after .remove() may be failed safely.
