From d0e0507ad6ccbeaad1f6bfe5923bdc5110df8636 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Tue, 28 Jul 2009 17:52:56 +0200 Subject: [PATCH] Staging: dst: correct error-handling code dst_state_alloc returns an ERR_PTR value in an error case instead of NULL. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // @match exists@ expression x, E; statement S1, S2; @@ x = dst_state_alloc(...) ... when != x = E ( * if (x == NULL || ...) S1 else S2 | * if (x == NULL && ...) S1 else S2 ) // Signed-off-by: Julia Lawall Signed-off-by: Greg Kroah-Hartman --- drivers/staging/dst/export.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/staging/dst/export.c b/drivers/staging/dst/export.c index 80ae4ebe610a..4fbd848bd14f 100644 --- a/drivers/staging/dst/export.c +++ b/drivers/staging/dst/export.c @@ -159,7 +159,7 @@ static struct dst_state *dst_accept_client(struct dst_state *st) goto err_out_exit; new = dst_state_alloc(st->node); - if (!new) { + if (IS_ERR(new)) { err = -ENOMEM; goto err_out_release; } -- 2.20.1
