One more thought...

Are there multiple drivers that need to follow this
pattern, or just one at the moment?  If just one driver,
then I would suggest open-coding accessing the property
in the probe routine instead of adding the helper
functions.  If more drivers appear with the same
pattern then the helper functions could be added.
