I think it can just go in the bin directly. I actually submitted a couple of
patches to clean up drivers/net/wan last year but didn't follow up
with a new version after we decided that x.25 is still needed, see
https://lore.kernel.org/netdev/20191209151256.2497534-1-arnd@arndb.de/

I can resubmit if you like.
