Dear TTY maintainers,

The CAN people (well, a subset) have spoken and decided to accept the
can327 driver (formerly elmcan), an ldisc based CAN driver allowing CAN
experiments with commodity hardware.

After several rounds of reviews, the final condition is for you to
accept this patch for N_CAN327, so here goes - please add this new line
discipline to the list, and once this filters through, the driver itself
will be added to can-next :)


Thanks!

Max
