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).
