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/soc_camera.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/drivers/media/platform/soc_camera/soc_camera.c b/drivers/media/platform/soc_camera/soc_camera.c index 10b57f8..a4beb6c 100644 --- a/drivers/media/platform/soc_camera/soc_camera.c +++ b/drivers/media/platform/soc_camera/soc_camera.c @@ -1184,7 +1184,8 @@ static int soc_camera_probe(struct soc_camera_device *icd) sd->grp_id = soc_camera_grp_id(icd); v4l2_set_subdev_hostdata(sd, icd); - if (v4l2_ctrl_add_handler(&icd->ctrl_handler, sd->ctrl_handler)) + ret = v4l2_ctrl_add_handler(&icd->ctrl_handler, sd->ctrl_handler); + if (ret) goto ectrl; /* At this point client .probe() should have run already */ -- 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
