From: Daniel Wagner <daniel.wagner@xxxxxxxxxxxx>
Loading firmware is an operation many drivers implement in various ways
around the completion API. And most of them do it almost in the same
way. Let's reuse the firmware_stat API which is used also by the
firmware_class loader. Apart of streamlining the firmware loading states
we also document it slightly better.
