Hi Bryan
It is good to look at other drivers and see how they work. Ideally,
your driver wants to look similar to all other drivers, so making the
maintenance easier.
You will find that most drivers have a set of goto statements for
error handling, which jump to the end of the function, and do cleanup.
No flags are maintained.
