The at9331 is only able to read or write a single register at once. The driver has a custom regmap bus and chooses to tell the regmap core about this by reporting the maximum transfer sizes rather than the explicit flags that exist at the regmap level. Since there are a number of problems with the raw transfer limits and the regmap level flags are better integrated anyway convert the driver to use the flags. No functional change.

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.
