ARM: SAMSUNG: question about cfg_eint field of struct s3c_gpio_cfg

[Joonyoung Shim]

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);
};
