regulator: pfuze100: Don't allocate an invalid gpio
Previously, the PFUZE100 would try to allocate gpio0 io0 because config.ena_gpio defaults to 0, which can be a valid GPIO. To prevent this from happening, set this parameter to -EINVAL. Signed-off-by: Sean Cross <xobs@kosagi.com> Signed-off-by: Mark Brown <broonie@linaro.org>
