[Severity: Low]
Since commit ce7c5382758b ("can: rcar_canfd: rcar_canfd_probe: Add struct
rcar_canfd_hw_info to driver data") changed the match data from an enum
value to a struct rcar_canfd_hw_info pointer and dereferenced info
without checking for NULL, should this include a Fixes tag?

  Fixes: ce7c5382758b ("can: rcar_canfd: rcar_canfd_probe: Add struct rcar_canfd_hw_info to driver data")

Also, rcar_canfd_probe() calls of_device_get_match_data() rather than
device_get_match_data().
