can: bittiming: can_fixup_bittiming(): set effective tq
The can_fixup_bittiming() function is used to validate the user-supplied low-level bit timing parameters and calculate the bitrate prescaler (brp) from the requested time quanta (tq) and the CAN clock of the controller. can_fixup_bittiming() selects the best matching integer bit rate prescaler, which may result in a different time quantum than the value specified by the user. Calculate the resulting time quantum and assign it so that the user sees the effective time quantum.
