When I attempt to shut down (or reboot) my R8 based NTC CHIP with this i2c driver I get the following error: "i2c i2c-0: mv64xxx: I2C bus locked, block: 1, time_left: 0". Reboots are successful but shutdowns freeze. If I comment out the shutdown routine the device both reboots and shuts down successfully without receiving this error (however it does receive a warning of missing atomic_xfer). It appears that very few i2c drivers have a shutdown method, I assume because these devices are often used to communicate with PMICs (such as in my case with the R8 based NTC CHIP). I'm proposing we simply remove this method so long as it doesn't cause trouble for others downstream. I'll work on an atomic_xfer method and submit that in a different patch.

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.
