From: Julia Lawall <julia.law...@lip6.fr> Remove unneeded error handling on the result of a call to platform_get_resource when the value is passed to devm_ioremap_resource.
Move the call to platform_get_resource adjacent to the call to devm_ioremap_resource to make the connection between them more clear. A simplified version of the semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression pdev,res,n,e,e1; expression ret != 0; identifier l; @@ - res = platform_get_resource(pdev, IORESOURCE_MEM, n); ... when != res - if (res == NULL) { ... \(goto l;\|return ret;\) } ... when != res + res = platform_get_resource(pdev, IORESOURCE_MEM, n); e = devm_ioremap_resource(e1, res); // </smpl> Signed-off-by: Julia Lawall <julia.law...@lip6.fr> --- drivers/input/keyboard/tegra-kbc.c | 7 +------ 1 file changed, 1 insertion(+), 6 deletions(-) diff --git a/drivers/input/keyboard/tegra-kbc.c b/drivers/input/keyboard/tegra-kbc.c index b46142f..9cd20e6 100644 --- a/drivers/input/keyboard/tegra-kbc.c +++ b/drivers/input/keyboard/tegra-kbc.c @@ -638,12 +638,6 @@ static int tegra_kbc_probe(struct platform_device *pdev) if (!tegra_kbc_check_pin_cfg(kbc, &num_rows)) return -EINVAL; - res = platform_get_resource(pdev, IORESOURCE_MEM, 0); - if (!res) { - dev_err(&pdev->dev, "failed to get I/O memory\n"); - return -ENXIO; - } - kbc->irq = platform_get_irq(pdev, 0); if (kbc->irq < 0) { dev_err(&pdev->dev, "failed to get keyboard IRQ\n"); @@ -658,6 +652,7 @@ static int tegra_kbc_probe(struct platform_device *pdev) setup_timer(&kbc->timer, tegra_kbc_keypress_timer, (unsigned long)kbc); + res = platform_get_resource(pdev, IORESOURCE_MEM, 0); kbc->mmio = devm_ioremap_resource(&pdev->dev, res); if (IS_ERR(kbc->mmio)) return PTR_ERR(kbc->mmio); -- 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/
