====================
pull-request: can 2018-01-04

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

The first patch is by Oliver Hartkopp, it improves the error checking
during the creation of a vxcan link. Wolfgang Grandegger's patch for the
gs_usb driver fixes the return value of the "set_bittiming" callback.
Luu An Phu provides a patch for the flexcan driver to fix the frame
length check in the flexcan_start_xmit() function. The last patch is by
Martin Lederhilger for the ems_usb driver and improves the error
reporting for error warning and passive frames.
