Merge tag 'linux-can-next-for-6.3-20230208' of git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can-next

Marc Kleine-Budde says:

====================
can-next 2023-02-08

The 1st patch is by Oliver Hartkopp and cleans up the CAN_RAW's
raw_setsockopt() for CAN_RAW_FD_FRAMES.

The 2nd patch is by me and fixes the compilation if
CONFIG_CAN_CALC_BITTIMING is disabled. (Problem introduced in last
pull request to next-next.)

* tag 'linux-can-next-for-6.3-20230208' of git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can-next:
  can: bittiming: can_calc_bittiming(): add missing parameter to no-op function
  can: raw: use temp variable instead of rolling back config
