Wayne Lin 3fb5155a39 drm/amd/display: Avoid updating surface with the same surface under MPO 
[ Upstream commit 1a38ded4bc ]

[Why & How]
Although it's dummy updates of surface update for committing stream
updates, we should not have dummy_updates[j].surface all indicating
to the same surface under multiple surfaces case. Otherwise,
copy_surface_update_to_plane() in update_planes_and_stream_state()
will update to the same surface only.

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.
