Lyude Paul 3e740fa80c drm/nouveau/kms/gv100-: Re-set LUT after clearing for modesets 
commit f287d3d19769b1d22cba4e51fa0487f2697713c9 upstream.

While certain modeset operations on gv100+ need us to temporarily
disable the LUT, we make the mistake of sometimes neglecting to
reprogram the LUT after such modesets. In particular, moving a head from
one encoder to another seems to trigger this quite often. GV100+ is very
picky about having a LUT in most scenarios, so this causes the display
engine to hang with the following error code:

disp: chid 1 stat 00005080 reason 5 [INVALID_STATE] mthd 0200 data
00000001 code 0000002d)

So, fix this by always re-programming the LUT if we're clearing it in a
state where the wndw is still visible, and has a XLUT handle programmed.

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 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.
