David Tolnay 16d444563a tpm: Prepare device implementation for handling send+recv together ... Cleanup only -- no functional change intended. A lot of the current TPM virtio device is closely based on previously existing virtio devices. This CL cleans up the TPM device in preparation for a change that will let it handle send+recv as a single descriptor chain. - Pass all EventFds together inside of the Worker object. - Introduce an Error enum to enable use of `?` error handling. - Introduce NeedsInterrupt enum to clarify meaning of return value of Worker::process_queue. - Simplify code for instantiating Worker and spawning thread.
