Hello Dave,

as there are still some things pending for the final 2.6.25 please add 
the following patch to fix the current documentation.

Thanks,
Oliver

------------------

The struct sockaddr_can has been simplified in the code review process. 
This patch updates this simplification also in the associated 
documentation in can.txt .
