clang static analysis reports this problem
tw5864-video.c:773:32: warning: The left expression of the compound
assignment is an uninitialized value.
The computed value will also be garbage
fintv->stepwise.max.numerator *= std_max_fps;
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ^
stepwise.max is set with frameinterval, which comes from
ret = tw5864_frameinterval_get(input, &frameinterval);
fintv->stepwise.step = frameinterval;
fintv->stepwise.min = frameinterval;
fintv->stepwise.max = frameinterval;
fintv->stepwise.max.numerator *= std_max_fps;
When tw5864_frameinterval_get() fails, frameinterval is not
set. So check the status and fix another similar problem.

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.
