[why] Do not need to spend time reprogramming DRR if there were no updates to the parameters. [how] Compare the current stream state to the requested one to determine if an update is required. In amdgpu_dm the timing_changed flag is set but never used so can remove it. Similarly, the stream update for VRR is done after dc_commit and should not update its adjust field until after the update is completed. The adjust field is managed by dc_stream_adjust_vmin_vmax and should not be manually updated in amdgpu_dm.

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.
