- * The completion callback is invoked in a context which can't sleep.
- * Before that invocation, the value of message->status is undefined.

- * core or controller driver code.

- * FIFO order, messages may go to different devices in other orders.
- * Some device might be higher priority, or have various "hard" access
- * time requirements, for example.
- *
- * On detection of any fault during the transfer, processing of
- * the entire message is aborted, and the device is deselected.
- * Until returning from the associated message completion callback,
