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.

MIPS folks: as mentioned in 00/54: either apply this directly
or ACK it and I will take it into the GPIO tree.
