commit 9a8f9320d67b27ddd7f1ee88d91820197a0e908f upstream.
At present, where repeated sends are intended to be used, the
i2c-microchip-core driver sends a stop followed by a start. Lots of i2c
devices must not malfunction in the face of this behaviour, because the
driver has operated like this for years! Try to keep track of whether or
not a repeated send is required, and suppress sending a stop in these
cases.

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.
