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/atmel_lcdfb.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/drivers/video/atmel_lcdfb.c b/drivers/video/atmel_lcdfb.c index 1505539..94cac9f 100644 --- a/drivers/video/atmel_lcdfb.c +++ b/drivers/video/atmel_lcdfb.c @@ -931,8 +931,10 @@ static int __init atmel_lcdfb_probe(struct platform_device *pdev) } info->screen_base = ioremap(info->fix.smem_start, info->fix.smem_len); - if (!info->screen_base) + if (!info->screen_base) { + ret = -ENOMEM; goto release_intmem; + } /* * Don't clear the framebuffer -- someone may have set @@ -960,6 +962,7 @@ static int __init atmel_lcdfb_probe(struct platform_device *pdev) sinfo->mmio = ioremap(info->fix.mmio_start, info->fix.mmio_len); if (!sinfo->mmio) { dev_err(dev, "cannot map LCDC registers\n"); + ret = -ENOMEM; goto release_mem; } -- 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
