Yes I'm able to reproduce the regression which is indeed caused by that
commit.

However I'm puzzled. Surely there is a fifth case I didn't cover because
when rfcomm_dev_state_change() is called, the tty_port is there but the tty is
not, and therefore I cannot get a reference to it and send the HUP.

I'll let you know when I have something working.
