Please don't use these obsolete S3C2410_GPIO_* defines, they will be
gone soon, if aren't yet.

Instead I would do something like:
8<-----------------------------------------------------------------
static const struct gpio gpios[] = {
{ S3C2410_GPF(4), GPIOF_OUT_INIT_HIGH, NULL },
{ S3C2410_GPF(5), GPIOF_OUT_INIT_HIGH, NULL },
{ S3C2410_GPF(6), GPIOF_OUT_INIT_HIGH, NULL },
{ S3C2410_GPF(7), GPIOF_OUT_INIT_HIGH, NULL },
};
if (!WARN_ON(gpio_request_array(gpios, ARRAY_SIZE(gpios)))
gpios_free_array(gpios);
/* W5300 interrupt pin. */
if (!WARN_ON(gpio_request(S3C2410_GPF(0), GPIOF_IN, NULL))) {
s3c_gpio_cfgpin(S3C2410_GPF(0), S3C_GPIO_SFN(2)); /* EINT0 */
gpio_free(S3C2410_GPF(0));
}
