Julian Parkin 556ec7a240 drm/amd/display: Program DWB watermarks from correct state
[ Upstream commit edb922b022c0c94805c4ffad202b3edff83d76f0 ]

[Why]
When diags adds a DWB via a stream update, we calculate MMHUBBUB
paramaters, but dc->current_state has not yet been updated
when the DWB programming happens. This leads to overflow on
high bandwidth tests since the incorrect MMHUBBUB arbitration
parameters are programmed.

[How]
Pass the updated context down to the (enable|update)_writeback functions
so that they can use the correct watermarks when programming MMHUBBUB.

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.
