Why is the value being passed as a reference and the error value (if
any), is not checked at all?

Shouldn't this just return the value as it obviously must always work?
(retorical question, something is wrong here...)

And this is a horrible global function name, can you prefix it with the
driver name to give us a chance to keep the global namespace sane?
vt6655_get_current_tsf() would be better.
