The structure 'dig' defines a member variable, (rx_gain_range_max) which is initialised to the value 'DM_DIG_MAX', (a defined constant). The variable is then used to test and set another variable. Since the member rx_gain_range_max is never assigned any other value then the constant 'DM_DIG_MAX' the code might as well simply use that constant, rather the a member variable set to that constant. The member variable has been removed and the constant used directly in the code. This is a coding style change which should not impact runtime code execution.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
