Since the vrr.guardband can now change for platforms that always use the VRR Timing Generator, and it is unsafe to reprogram the guardband on the fly, move the guardband and pipeline_full checks from the pure !fastboot path and add a check for intel_vrr_always_use_vrr_tg(). For older platforms the vrr.guardband change happens when VRR Timing generator is off. For the platforms that always use the VRR Timing Generator, this will prevent reprogramming the vrr.guardband without a full modeset. However, this will disrupt LRR functionality for these platforms. v2: Modify the check to avoid breaking the LRR on older platform. (Ville) v3: Correct the oversight of not removing the lines from the original location.

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.
