gpio: xgene: fix type of variable containing error codes
ret variable can contain error values and is compared with zero. Its type must be signed. The problem has been detected using coccinelle script scripts/coccinelle/tests/unsigned_lesser_than_zero.cocci Signed-off-by: Andrzej Hajda <a.hajda@samsung.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
