Chris Wilson 0d55babc83 drm/i915: Drop stray clearing of rps->last_adj
We used to reset last_adj to 0 on crossing a power domain boundary, to
slow down our rate of change. However, commit 60548c554b ("drm/i915:
Interactive RPS mode") accidentally caused it to be reset on every
frequency update, nerfing the fast response granted by the slow start
algorithm.

Fixes: 60548c554b ("drm/i915: Interactive RPS mode")
Testcase: igt/pm_rps/mix-max-config-loaded

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
