The OR here seems a bit odd, my preference would be how Andy suggested
initially ...

    gpio->secure = devm_platform_ioremap_resource_byname(pdev, "security");
    if (IS_ERR(gpio->secure)) {
        gpio->secure = devm_platform_ioremap_resource(pdev, 0);
        if (IS_ERR(gpio->secure))
            return PTR_ERR(gpio->secure)
    }

Cheers
Jon
