unicore: gpio: Be sure to clamp return value
As we want gpio_chip .get() calls to be able to return negative error codes and propagate to drivers, we need to go over all drivers and make sure their return values are clamped to [0,1]. We do this by using the ret = !!(val) design pattern. Cc: Guan Xuetao <gxt@mprc.pku.edu.cn> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
