In commit b05ae01fdb89, someone tried to make the driver handle i2c read
errors by simply zeroing out the register contents, but for some reason
left unaltered the code that sets the cached register value the function
call return value.
The original patch was authored by a member of the Underhanded
Mangle-happy Nerds, I'm not terribly surprised. I don't have the
hardware anymore so I can't test this, but it seems like a pretty
obvious API usage fix to me...

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.
