That doesn't make much sense anyway. If the firmware filename is
foo-$APIVER-$CODEVER every code change would need a corresponding driver
change. If it is just foo-$APIVER then the $CODEVER can be embedded in
the firmware file and printed so you know which code you're using, but
if it doesn't influence the API I don't see why it should be part of the
filename?
