Subject: error: too many arguments to function ‘can_calc_bittiming’

Hi,

It's possible to have a kernel .config (randconfig) file with
# CONFIG_CAN_CALC_BITTIMING is not set

which ends up with different number of arguments to can_calc_bittiming().

Full compiler error listing is:

../drivers/net/can/dev/bittiming.c: In function ‘can_get_bittiming’:
../drivers/net/can/dev/bittiming.c:145:24: error: too many arguments to function ‘can_calc_bittiming’
  145 |                 return can_calc_bittiming(dev, bt, btc, extack);
      |                        ^~~~~~~~~~~~~~~~~~
In file included from ../include/linux/can/dev.h:18,
                 from ../drivers/net/can/dev/bittiming.c:7:
../include/linux/can/bittiming.h:126:1: note: declared here
  126 | can_calc_bittiming(const struct net_device *dev, struct can_bittiming *bt,
      | ^~~~~~~~~~~~~~~~~~


A failing i386 .config file is attached.

Do you have any suggestions for resolving this error?

Thank you.
