Rob, I looked at the history of patches to this driver and all them 
included changes to the documentation in the same patch so I followed a 
similar model. I assumed that a separate patch was only required when 
the documentation was being added from scratch and not when modifying a 
few lines. Is this not the case?

As mentioned before, these changes to the documentation  will be undone 
in V2. Thanks
