From: Julia Lawall <julia.law...@lip6.fr> Set the return variable to an error code as done elsewhere in the function.
A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> ( if@p1 (\(ret < 0\|ret != 0\)) { ... return ret; } | ret@p1 = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // </smpl> Signed-off-by: Julia Lawall <julia.law...@lip6.fr> --- Not tested. drivers/net/hamradio/6pack.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/drivers/net/hamradio/6pack.c b/drivers/net/hamradio/6pack.c index 1450e33..66e2b19 100644 --- a/drivers/net/hamradio/6pack.c +++ b/drivers/net/hamradio/6pack.c @@ -662,7 +662,8 @@ static int sixpack_open(struct tty_struct *tty) tty->receive_room = 65536; /* Now we're ready to register. */ - if (register_netdev(dev)) + err = register_netdev(dev); + if (err) goto out_free; tnc_init(sp); -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
