====================
pull-request: can 2020-11-30
The first patch is by me an target the tcan4x5x bindings for the m_can driver.
It fixes the error path in the tcan4x5x_can_probe() function.
The next two patches are by Jeroen Hofstee and makes the lost of arbitration
error counters of sja1000 and the sun4i drivers consistent with the other
drivers.
Zhang Qilong contributes two patch that clean up the error path in the c_can
and kvaser_pciefd drivers.
