From: Julia Lawall <julia@xxxxxxx> str has already been tested. It seems that this test should be on the recently returned value snr. A simplified version of the semantic match that finds this problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @r exists@ local idexpression x; expression E; @@ if (x == NULL || ...) { ... when forall return ...; } ... when != \(x=E\|x--\|x++\|--x\|++x\|x-=E\|x+=E\|x|=E\|x&=E\|&x\) ( *x == NULL | *x != NULL ) // </smpl> Signed-off-by: Julia Lawall <julia@xxxxxxx> --- drivers/atm/solos-pci.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/drivers/atm/solos-pci.c b/drivers/atm/solos-pci.c index 9359613..307321b 100644 --- a/drivers/atm/solos-pci.c +++ b/drivers/atm/solos-pci.c @@ -372,7 +372,7 @@ static int process_status(struct solos_card *card, int port, struct sk_buff *skb } snr = next_string(skb); - if (!str) + if (!snr) return -EIO; attn = next_string(skb); if (!attn) -- 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
