This series fixes an overflow bug in tty_wait_until_sent, which is
currently broken on 64-bit machines for most TTY drivers (with
serial-core being the notable exception).

The final patch makes the tty_wait_until_sent timeout a maximum one so
that we actually honour the closing-wait timeout.

All but the second (clean-up) and final patch are marked for stable.

These patches are for v4.0 and I suggest Greg takes them all through the
TTY tree.

Nice fixes, all now queued up.
