this is a pull request of 4 patches for net-next/master.

Arnd Bergmann's patch fixes a regresseion in af_can introduced in
linux-can-next-for-4.8-20160617. There are two patches by Ramesh
Shanmugasundaram, which add CAN-2.0 support to the rcar_canfd driver.
And a patch by Ed Spiridonov that adds better error diagnoses messages
to the Ed Spiridonov driver.
