If isochronous contexts existed when firewire-ohci was unloaded, the core iso shutdown functions crashed with NULL dereferences, and buffers etc. weren't released. How the fix works: We first copy the card driver's iso shutdown hooks into the dummy driver, then fw_destroy_nodes notifies upper layers of devices going away, these should shut down (including their iso contexts), wait_for_completion(&card->done) will be triggered after upper layers gave up all fw_device references, after which the card driver's shutdown proceeds.
