====================
pull-request: can 2017-10-24
here's another pull request for net/master.
The patch by Gerhard Bertelsmann fixes the CAN_CTRLMODE_LOOPBACK in the
sun4i driver. Two patches by Jimmy Assarsson for the kvaser_usb driver
fix a print in the error path of the kvaser_usb_close() and remove a
wrong warning message with the Leaf v2 firmware version v4.1.844.
