Ensure that conversion mode is successfully exited when the command is issued by adding an extra transfer beforehand, matching the minimum CNV high and low times from the AD4695 datasheet. The AD4695 has a quirk where the exit command only works during a conversion, so guarantee this happens by triggering a conversion in ad4695_exit_conversion_mode(). Then make this even more robust by ensuring that the exit command is run at AD4695_REG_ACCESS_SCLK_HZ rather than the bus maximum.

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 reStructuredText 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.
