From: Peter Senna Tschudin <[email protected]> Convert a nonnegative error return code to a negative one, as returned 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: Peter Senna Tschudin <[email protected]> --- drivers/net/irda/mcs7780.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/drivers/net/irda/mcs7780.c b/drivers/net/irda/mcs7780.c index 1a00b59..f07c340 100644 --- a/drivers/net/irda/mcs7780.c +++ b/drivers/net/irda/mcs7780.c @@ -920,8 +920,10 @@ static int mcs_probe(struct usb_interface *intf, ndev->netdev_ops = &mcs_netdev_ops; - if (!intf->cur_altsetting) + if (!intf->cur_altsetting) { + ret = -ENOMEM; goto error2; + } ret = mcs_find_endpoints(mcs, intf->cur_altsetting->endpoint, intf->cur_altsetting->desc.bNumEndpoints); -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
