[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) Signed-off-by: Zaur Kambarov <zkambarov@coverity.com> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
