Alex Deucher 245ff08e26 Revert "drm/amd/display: pause the workload setting in dm" 
[ Upstream commit f377ea0561 ]

This reverts commit bc6d54ac7e.

The workload profile needs to be in the default state when
the dc idle optimizaion state is entered.  However, when
jobs come in for video or GFX or compute, the profile may
be set to a non-default profile resulting in the dc idle
optimizations not taking affect and resulting in higher
power usage.  As such we need to pause the workload profile
changes during this transition.  When this patch was originally
committed, it caused a regression with a Dell U3224KB display,
but no other problems were reported at the time.  When it
was reapplied (this patch) to address increased power usage, it
seems to have caused additional regressions.  This change seems
to have a number of side affects (audio issues, stuttering,
etc.).  I suspect the pause should only happen when all displays
are off or in static screen mode, but I think this call site
gets called more often than that which results in idle state
entry more often than intended.  For now revert.

README 

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.
