Recent versions of checkpatch complain that struct regmap_config should be declared as const. WARNING: struct regmap_config should normally be const Doing so reveals a potential problem in the driver: If both supported chips are present in a single system, the maximum number of registers may race when devices are instantiated since max_registers is updated in the probe function. Solve the problem by setting .max_registers to the maximum register address of all supported chips. This does not make a practical difference while fixing the potential race condition and reducing code complexity.

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.
