From: Peter Senna Tschudin <peter.senna@xxxxxxxxx> 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.senna@xxxxxxxxx> --- drivers/video/exynos/exynos_mipi_dsi.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/drivers/video/exynos/exynos_mipi_dsi.c b/drivers/video/exynos/exynos_mipi_dsi.c index c4f25de..07d70a3 100644 --- a/drivers/video/exynos/exynos_mipi_dsi.c +++ b/drivers/video/exynos/exynos_mipi_dsi.c @@ -375,6 +375,7 @@ static int exynos_mipi_dsi_probe(struct platform_device *pdev) dsim->clock = clk_get(&pdev->dev, "dsim0"); if (IS_ERR(dsim->clock)) { dev_err(&pdev->dev, "failed to get dsim clock source\n"); + ret = -ENODEV; goto err_clock_get; } @@ -383,6 +384,7 @@ static int exynos_mipi_dsi_probe(struct platform_device *pdev) res = platform_get_resource(pdev, IORESOURCE_MEM, 0); if (!res) { dev_err(&pdev->dev, "failed to get io memory region\n"); + ret = -ENODEV; goto err_platform_get; } @@ -407,6 +409,7 @@ static int exynos_mipi_dsi_probe(struct platform_device *pdev) dsim_ddi = exynos_mipi_dsi_bind_lcd_ddi(dsim, dsim_pd->lcd_panel_name); if (!dsim_ddi) { dev_err(&pdev->dev, "mipi_dsim_ddi object not found.\n"); + ret = -EINVAL; goto err_bind; } -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
