gpio: pca953x: initialize ret to zero to avoid returning garbage
ret is not initialized so it contains garbage. Ensure garbage is not returned in the case that pdata && pdata->teardown is false by initializing ret to 0. Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
