What's wrong with the following (drivers/input/serio/serio.c):

static struct device_attribute serio_device_attrs[] = {
        __ATTR(description, S_IRUGO, serio_show_description, NULL),
        __ATTR(driver, S_IWUSR | S_IRUGO, serio_show_driver, serio_rebind_driver),
        __ATTR(bind_mode, S_IWUSR | S_IRUGO, serio_show_bind_mode, serio_set_bind_mode),
        __ATTR_NULL
};

Pretty compact and expressive IMHO.
