From: Julia Lawall <julia.law...@lip6.fr> 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.law...@lip6.fr> --- drivers/usb/musb/musb_dsps.c | 3 --- 1 file changed, 3 deletions(-) diff --git a/drivers/usb/musb/musb_dsps.c b/drivers/usb/musb/musb_dsps.c index 4ffbaac..f2f9710 100644 --- a/drivers/usb/musb/musb_dsps.c +++ b/drivers/usb/musb/musb_dsps.c @@ -357,9 +357,6 @@ static int dsps_musb_init(struct musb *musb) u32 rev, val; r = platform_get_resource_byname(parent, IORESOURCE_MEM, "control"); - if (!r) - return -EINVAL; - reg_base = devm_ioremap_resource(dev, r); if (!musb->ctrl_base) return -EINVAL; -- 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/
