====================
pull-request: can-next 2017-12-01,Re: pull-request: can-next

this is a pull request of 7 patches for net-next/master.

All patches are by me. Patch 6 is for the "can_raw" protocol and add
error checking to the bind() function. All other patches clean up the
coding style and remove unused parameters in various CAN drivers and
infrastructure.
