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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
