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/video/cg3.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/drivers/video/cg3.c b/drivers/video/cg3.c index f927a7b..c5e7612 100644 --- a/drivers/video/cg3.c +++ b/drivers/video/cg3.c @@ -398,7 +398,8 @@ static int __devinit cg3_probe(struct platform_device *op) goto out_unmap_screen; } - if (fb_alloc_cmap(&info->cmap, 256, 0)) + err = fb_alloc_cmap(&info->cmap, 256, 0); + if (err) goto out_unmap_screen; fb_set_cmap(&info->cmap, info); -- 1.7.11.4 -- 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/
