Modified files:
sys/dev/sio sio.c
Log:
If you insert a pccard modem and then eject it, you get a panic. This
happens because the sio device was never opened and com->tp is
therefore NULL. ttygone can't swallow a NULL, so guard against that
possibility. Other places in this function make similar checks, so I
believe this is correct.
