From: Julia Lawall <julia@xxxxxxx> The result of container_of should not be NULL. In particular, in this case the argument to the enclosing function has passed though INIT_WORK, which dereferences it, implying that its container cannot be NULL. The semantic match that finds this problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression x,e; @@ x = container_of(...) ... when != x = e * x == NULL // </smpl> Signed-off-by: Julia Lawall <julia@xxxxxxx> --- net/irda/ircomm/ircomm_tty.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/net/irda/ircomm/ircomm_tty.c b/net/irda/ircomm/ircomm_tty.c index 811984d..6306c19 100644 --- a/net/irda/ircomm/ircomm_tty.c +++ b/net/irda/ircomm/ircomm_tty.c @@ -609,7 +609,7 @@ static void ircomm_tty_do_softint(struct work_struct *work) IRDA_DEBUG(2, "%s()\n", __func__ ); - if (!self || self->magic != IRCOMM_TTY_MAGIC) + if (self->magic != IRCOMM_TTY_MAGIC) return; tty = self->tty; -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
