Date: Mon, 10 Jan 2011 17:28:27 +0100 From: Clemens Ladisch Subject: firewire: cdev: remove unneeded idr_find() from complete_transaction() Outbound transactions are never aborted with release_client_resource(), so it is not necessary for complete_transaction() to check whether the resource is still registered. Only shutdown_resource() can abort such an transaction, and this is already handled with the in_shutdown check.
