From: Sean Wang <sean.wang@mediatek.com>

EINT_NA is an u16 number, so it should be U16_MAX instead of -1
to fix up drivers/pinctrl/mediatek/pinctrl-paris.c:732 mtk_gpio_to_irq()
warn: impossible condition (desc->eint.eint_n == -1) => (0-u16max == (-1))

Also happens in
drivers/pinctrl/mediatek/pinctrl-paris.c:749 mtk_gpio_set_config()
warn: impossible condition (desc->eint.eint_n == -1) => (0-u16max == (-1))

drivers/pinctrl/mediatek/pinctrl-moore.c:479 mtk_gpio_to_irq()
warn: impossible condition (desc->eint.eint_n == -1) => (0-u16max == (-1))

drivers/pinctrl/mediatek/pinctrl-moore.c:496 mtk_gpio_set_config()
warn: impossible condition '(desc->eint.eint_n == -1) => (0-u16max == (-1))
