From: Peter Senna Tschudin <peter.se...@gmail.com> 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.se...@gmail.com> --- drivers/media/platform/soc_camera/mx2_camera.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/drivers/media/platform/soc_camera/mx2_camera.c b/drivers/media/platform/soc_camera/mx2_camera.c index 256187f..01d7c11 100644 --- a/drivers/media/platform/soc_camera/mx2_camera.c +++ b/drivers/media/platform/soc_camera/mx2_camera.c @@ -1800,12 +1800,14 @@ static int __devinit mx2_camera_probe(struct platform_device *pdev) if (!res_emma || !irq_emma) { dev_err(&pdev->dev, "no EMMA resources\n"); + err = -ENODEV; goto exit_free_irq; } pcdev->res_emma = res_emma; pcdev->irq_emma = irq_emma; - if (mx27_camera_emma_init(pcdev)) + err = mx27_camera_emma_init(pcdev); + if (err) goto exit_free_irq; } -- 1.7.11.4 -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
