[PATCH v3 07/11] drm: Store new plane state in a variable for atomic_update and disable

From: Maxime Ripard
Date: Fri Feb 19 2021 - 07:04:51 EST

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:

(
static const struct drm_plane_helper_funcs helpers = {

...,

)
