[Why] When sending DCC with Stereo, DCC gets enabled but the meta addresses are 0. This happens momentarily before the meta addresses are populated with a valid address. [How] Add call validate_dcc_with_meta_address() in copy_surface_update_to_plane() to check for surface address and DCC change. When DCC has changed, check if DCC enable is true but meta address is 0. If so, we turn DCC enable to false. When surface address has changed, we check if DCC enable is false but meta address is not 0. If so, we turn DCC enable back to true. This will restore DCC enable to the proper setting once the meta address is valid.

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.
