ARM: SAMSUNG: question about cfg_eint field of struct s3c_gpio_cfg

[Joonyoung Shim <jy0922.shim@xxxxxxxxxxx>]

Hi,

There is cfg_eint field in struct s3c_gpio_cfg at 
arch/arm/plat-samsung/include/plat/gpio-cfg.h. I don't know the usage of 
cfg_eint. It isn't used anywhere or just assigned. Does it need really?

struct s3c_gpio_cfg {
	unsigned int	cfg_eint;

	s3c_gpio_pull_t	(*get_pull)(struct s3c_gpio_chip *chip, unsigned offs);
	int		(*set_pull)(struct s3c_gpio_chip *chip, unsigned offs,
				    s3c_gpio_pull_t pull);

	unsigned (*get_config)(struct s3c_gpio_chip *chip, unsigned offs);
	int	 (*set_config)(struct s3c_gpio_chip *chip, unsigned offs,
			       unsigned config);
};
