commit 1465d06a6d8580e73ae65f8590392df58c5ed2fd upstream. The fields 'opened', 'running', 'assigned_key' are all protected by a spinlock, but the spinlock is not taken when looking for a stream. This can result in a possible race between assign() and release(). Fix by taking the spinlock before walking through the bus stream list.
