Linus Walleij 80776df4f5 gpio: viperboard: 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.
