it's already checked in devm_ioremap_resource in a better way,

void __iomem *devm_ioremap_resource(struct device *dev, struct resource *res)
 {
...
         if (!res || resource_type(res) != IORESOURCE_MEM) {
                 dev_err(dev, "invalid resource\n");
                 return ERR_PTR(-EINVAL);
         }
...
