commit e20538b8 ("gpio: Propagate errors from chip->get()") started to propagate errors from the .get() functions since we can get errors from the infrastructure of e.g. slowbus GPIO expanders. However it turns out a bunch of drivers relied on the core to clamp the value, so we need to revert to the old behaviour and go over all drivers and fix them to conform to the expectations of the core before we go back to propagating the error code.
