iio: dac: ad5686: Don't set error code to voltage_uv
regulator_get_voltage() may return negative error code. Add error checking to avoid setting error code to voltage_uv. Signed-off-by: Axel Lin <axel.lin@ingics.com> Acked-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
