pinctrl: mediatek: check mtk_is_virt_gpio input parameter
check mtk_is_virt_gpio input parameter, virtual gpio need to support eint mode. add error handler for the ko case to fix this boot fail: pc : mtk_is_virt_gpio+0x20/0x38 [pinctrl_mtk_common_v2] lr : mtk_gpio_get_direction+0x44/0xb0 [pinctrl_paris] Fixes: edd546465002 ("pinctrl: mediatek: avoid virtual gpio trying to set reg") Signed-off-by: Hanks Chen <hanks.chen@mediatek.com> Acked-by: Sean Wang <sean.wang@kernel.org> Singed-off-by: Jie Yang <sin_jieyang@mediatek.com> Link: https://lore.kernel.org/r/1597922546-29633-1-git-send-email-hanks.chen@mediatek.com Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
