drm: Store new plane state in a variable for atomic_update and disable
In order to store the new plane state in a subsequent helper, let's move
the plane->state dereferences into a variable.

This was done using the following coccinelle script, plus some hand
changes for vmwgfx:

@ plane_atomic_func @
identifier helpers;
identifier func;

(
 static const struct drm_plane_helper_funcs helpers = {
 	...,
 	.atomic_disable = func,

 };

 	...,
 	.atomic_update = func,
	...,
 };

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.
