[PATCH] coverity: tty_ldisc_ref return null check
We add a check of the return value of tty_ldisc_ref(), which
is checked 7 out of 8 times, e.g.:
149 ld = tty_ldisc_ref(tty);
150 if (ld != NULL) {
151 if (ld->set_termios)
152 (ld->set_termios)(tty, &old_termios);
153 tty_ldisc_deref(ld);
154 }
This defect was found automatically by Coverity Prevent, a static analysis
tool.
(akpm: presumably `ld' is never NULL. Oh well)
