From: Peter Senna Tschudin <peter.senna@xxxxxxxxx> 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 <peter.senna@xxxxxxxxx> --- drivers/video/bw2.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/drivers/video/bw2.c b/drivers/video/bw2.c index 7ba74cd..6bea9a9 100644 --- a/drivers/video/bw2.c +++ b/drivers/video/bw2.c @@ -319,8 +319,10 @@ static int __devinit bw2_probe(struct platform_device *op) info->screen_base = of_ioremap(&op->resource[0], 0, info->fix.smem_len, "bw2 ram"); - if (!info->screen_base) + if (!info->screen_base) { + err = -ENOMEM; goto out_unmap_regs; + } bw2_blank(FB_BLANK_UNBLANK, info); -- 1.7.11.4 -- 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
