Ankit Nautiyal 0ead88112b drm/i915/vrr: Avoid reading vrr.enable based on fixed_rr check
Currently, vrr.enable is intended only for variable refresh rate timings.
At this point, we do not set fixed refresh rate timings, but the GOP can,
which creates a problem during the readback of vrr.enable.

The GOP enables the VRR timing generator with fixed timings, while the
driver only recognizes the VRR timing generator as enabled with
variable timings. This discrepancy causes an issue due to the
fixed refresh rate check during readback. Since the VRR timing generator
is enabled and we do not support fixed timings, the readback should set
vrr.enable so that the driver can disable the VRR timing generator.
However, the current check does not allow this.

Therefore, remove the fixed refresh rate check during readback.

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.
