From: Peter Senna Tschudin <[email protected]> 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 <[email protected]> --- drivers/media/platform/omap3isp/isp.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/drivers/media/platform/omap3isp/isp.c b/drivers/media/platform/omap3isp/isp.c index e0096e0..91fcaef 100644 --- a/drivers/media/platform/omap3isp/isp.c +++ b/drivers/media/platform/omap3isp/isp.c @@ -2102,8 +2102,10 @@ static int __devinit isp_probe(struct platform_device *pdev) if (ret < 0) goto error; - if (__omap3isp_get(isp, false) == NULL) + if (__omap3isp_get(isp, false) == NULL) { + ret = -EBUSY; /* Not sure if EBUSY is best for here */ goto error; + } ret = isp_reset(isp); if (ret < 0) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
