From: Julia Lawall <Julia.Lawall@xxxxxxx> 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.Lawall@xxxxxxx> --- drivers/pinctrl/pinctrl-nomadik.c | 5 +---- 1 file changed, 1 insertion(+), 4 deletions(-) diff --git a/drivers/pinctrl/pinctrl-nomadik.c b/drivers/pinctrl/pinctrl-nomadik.c index 89280bc..be126fc 100644 --- a/drivers/pinctrl/pinctrl-nomadik.c +++ b/drivers/pinctrl/pinctrl-nomadik.c @@ -1055,10 +1055,6 @@ static int nmk_gpio_probe(struct platform_device *dev) pdata->num_gpio = NMK_GPIO_PER_CHIP; } - res = platform_get_resource(dev, IORESOURCE_MEM, 0); - if (!res) - return -ENOENT; - irq = platform_get_irq(dev, 0); if (irq < 0) return irq; @@ -1067,6 +1063,7 @@ static int nmk_gpio_probe(struct platform_device *dev) if (secondary_irq >= 0 && !pdata->get_secondary_status) return -EINVAL; + res = platform_get_resource(dev, IORESOURCE_MEM, 0); base = devm_ioremap_resource(&dev->dev, res); if (IS_ERR(base)) return PTR_ERR(base); -- 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
