    powerpc: qe_lib/gpio: Be sure to clamp return value · e847396b
    Linus Walleij authored
    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.
