When using a fixed mode we won't change the refresh rate ever. So filter out all modes that don't match the fixed_mode's refresh rate. I'm going to declare the "rounded to nearest Hz refresh rates must match" approach good enough for now. Note that we could start supporting multiple refresh rates with panels that can do it, but that would mean replacing the single fixed mode concept with a list of fixed modes. Then we could look for the closest match to the user's requested refresh rate and use that. But all of that would be a fair bit of work so we'll leave it for later.

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.
