This doesn't appear to be a tty device ?

Hardly true. A tty driver has a very precisely defined set of behaviours
and a lot of ioctls and interfaces your driver doesn't. Our gps
interfaces are only tty drivers because historically they were plugged
into serial ports so I'm not sure the 'not a tty' bit actually matters.

Codewise its the same as all the rest - only one instance possible and
poking around in globals with no visible or documented locking.
