[PATCH 1/4] Revert "gpio: generic: clamp retured value to [0,1]"

[Vladimir Zapolskiy <vladimir_zapolskiy@xxxxxxxxxx>]

This reverts commit 25b35da7f4cce82271859f1b6eabd9f3bd41a2bb.

The original change is a fast workaround in GPIO generic driver,
which is properly fixed by Alexandre's 23600969ff centralized handling
of return values from GPIO chip drivers.

To avoid a redundant check and copy/paste confusion, it is better to
revert the change done in a particular driver.
