    sys/kern             tty.c 
  Log:
  MFC rev. 1.279:
  
  The dev_refthread() in the tty_gettp() may fail, because Giant is taken
  in the giant_trick routines after the dev_refthread increments the
  si_threadcount. Remove assert, do not perform dev_relthread() for failed
  dev_refthread(), and handle failure in the tty_gettp() callers (cdevsw
  tty methods).
