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/mmc/host/mxs-mmc.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/mmc/host/mxs-mmc.c b/drivers/mmc/host/mxs-mmc.c index 80d1e6d..afd8fdd 100644 --- a/drivers/mmc/host/mxs-mmc.c +++ b/drivers/mmc/host/mxs-mmc.c @@ -674,6 +674,7 @@ static int mxs_mmc_probe(struct platform_device *pdev) if (!ssp->dmach) { dev_err(mmc_dev(host->mmc), "%s: failed to request dma\n", __func__); + ret = -ENODEV; goto out_clk_put; } -- 1.7.11.4 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
