firewire: fully initialize fw_transaction before marking it pending
In theory, card->flush_timer could already access a transaction between fw_send_request()'s spin_unlock_irqrestore and the rest of what happens in fw_send_request(). This would happen if the process which sends the request is preempted and put to sleep right after spin_unlock_irqrestore for longer than 100ms. Therefore we fill in everything in struct fw_transaction at which the flush_timer might look at before we lift the lock. To do: Ensure that the timer does not pick up the transaction before the time of the AT request event plus split transaction timeout. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
