Subject: [PATCH net-next 31/47] can: bittiming(): replace open coded variants of can_bit_time()
Commit 1c47fa6b31c2 ("can: dev: add a helper function to calculate the
duration of one bit") added the helper function can_bit_time().
Replace open coded variants of can_bit_time() by the helper function.
