From: Julia Lawall <Julia.Lawall@xxxxxxx> Remove unneeded error handling on the result of a call to platform_get_resource_byname when the value is passed to devm_ioremap_resource. A simplified version of the semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression pdev,res,e,e1; expression ret != 0; identifier l; @@ res = platform_get_resource_byname(...); - if (res == NULL) { ... \(goto l;\|return ret;\) } e = devm_ioremap_resource(e1, res); // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@xxxxxxx> --- drivers/regulator/ti-abb-regulator.c | 10 ---------- 1 file changed, 10 deletions(-) diff --git a/drivers/regulator/ti-abb-regulator.c b/drivers/regulator/ti-abb-regulator.c index 3753ed0..d8e3e12 100644 --- a/drivers/regulator/ti-abb-regulator.c +++ b/drivers/regulator/ti-abb-regulator.c @@ -717,11 +717,6 @@ static int ti_abb_probe(struct platform_device *pdev) /* Map ABB resources */ pname = "base-address"; res = platform_get_resource_byname(pdev, IORESOURCE_MEM, pname); - if (!res) { - dev_err(dev, "Missing '%s' IO resource\n", pname); - ret = -ENODEV; - goto err; - } abb->base = devm_ioremap_resource(dev, res); if (IS_ERR(abb->base)) { ret = PTR_ERR(abb->base); @@ -770,11 +765,6 @@ static int ti_abb_probe(struct platform_device *pdev) pname = "ldo-address"; res = platform_get_resource_byname(pdev, IORESOURCE_MEM, pname); - if (!res) { - dev_dbg(dev, "Missing '%s' IO resource\n", pname); - ret = -ENODEV; - goto skip_opt; - } abb->ldo_base = devm_ioremap_resource(dev, res); if (IS_ERR(abb->ldo_base)) { ret = PTR_ERR(abb->ldo_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
