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/s5p-tv/sdo_drv.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/drivers/media/platform/s5p-tv/sdo_drv.c b/drivers/media/platform/s5p-tv/sdo_drv.c index ad68bbe..58cf56d 100644 --- a/drivers/media/platform/s5p-tv/sdo_drv.c +++ b/drivers/media/platform/s5p-tv/sdo_drv.c @@ -369,6 +369,7 @@ static int __devinit sdo_probe(struct platform_device *pdev) sdev->fout_vpll = clk_get(dev, "fout_vpll"); if (IS_ERR_OR_NULL(sdev->fout_vpll)) { dev_err(dev, "failed to get clock 'fout_vpll'\n"); + ret = -ENXIO; goto fail_dacphy; } dev_info(dev, "fout_vpll.rate = %lu\n", clk_get_rate(sclk_vpll)); @@ -377,11 +378,13 @@ static int __devinit sdo_probe(struct platform_device *pdev) sdev->vdac = devm_regulator_get(dev, "vdd33a_dac"); if (IS_ERR_OR_NULL(sdev->vdac)) { dev_err(dev, "failed to get regulator 'vdac'\n"); + ret = -ENXIO; goto fail_fout_vpll; } sdev->vdet = devm_regulator_get(dev, "vdet"); if (IS_ERR_OR_NULL(sdev->vdet)) { dev_err(dev, "failed to get regulator 'vdet'\n"); + ret = -ENXIO; goto fail_fout_vpll; } -- 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/
