====================
pull-request: can-next 2019-08-14

this is a pull request for net-next/master consisting of 41 patches.

The first two patches are for the kvaser_pciefd driver: Christer Beskow
removes unnecessary code in the kvaser_pciefd_pwm_stop() function,
YueHaibing removes the unused including of <linux/version.h>.

In the next patch YueHaibing also removes the unused including of
<linux/version.h> in the f81601 driver.

In the ti_hecc driver the next 6 patches are by me and fix checkpatch
warnings. YueHaibing's patch removes an unused variable in the
ti_hecc_mailbox_read() function.

The next 6 patches all target the xilinx_can driver. Anssi Hannula's
patch fixes a chip start failure with an invalid bus. The patch by
Venkatesh Yadav Abbarapu skips an error message in case of a deferred
probe. The 3 patches by Appana Durga Kedareswara rao fix the RX and TX
path for CAN-FD frames. Srinivas Neeli's patch fixes the bit timing
calculations for CAN-FD.

The next 12 patches are by me and several checkpatch warnings in the
af_can, raw and bcm components.

Thomas Gleixner provides a patch for the bcm, which switches the timer
to HRTIMER_MODE_SOFT and removes the hrtimer_tasklet.

Then 6 more patches by me for the gw component, which fix checkpatch
warnings, followed by 2 patches by Oliver Hartkopp to add CAN-FD
support.

The vcan driver gets 3 patches by me, fixing checkpatch warnings.

And finally a patch by Andre Hartmann to fix typos in CAN's netlink
header.
