When built without CONFIG_PWM there are no references to
ti_sn65dsi86_read_u16(), avoid the W=1 build warning by marking the
function as __maybe_unused.
__maybe_unused is used insted of a #ifdef guard as it looks slighly
cleaner and it avoids issues if in the future other permutations of the
config options would use the function.

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.
