The change converts the probe function to use the devm_iio_device_register() function. Before calling that, we need to register an action to store the wiper back to non-volatile memory when the device is de-registered. We don't need to do this if the probe fails, because the only place where the probe can fail now is devm_iio_device_register() and that shouldn't create an IIO device (for userspace to poke at) if it fails.
