From ab99cb18ae5cbb93f650ba7bc305aae6155da880 Mon Sep 17 00:00:00 2001 From: Peter Senna Tschudin Date: Thu, 6 Sep 2012 12:24:00 -0300 Subject: [PATCH] [media] drivers/media/platform/soc_camera/soc_camera.c: fix error return code 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/) // ( if@p1 (\(ret < 0\|ret != 0\)) { ... return ret; } | ret@p1 = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // Signed-off-by: Peter Senna Tschudin [g.liakhovetski@gmx.de: follow the soc_camera.c style: check "ret < 0"] Signed-off-by: Guennadi Liakhovetski Signed-off-by: Mauro Carvalho Chehab --- 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 96c3c6e83cc0..d3f0b84e2d70 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, NULL)) + ret = v4l2_ctrl_add_handler(&icd->ctrl_handler, sd->ctrl_handler, NULL); + if (ret < 0) goto ectrl; /* At this point client .probe() should have run already */ -- 2.20.1
