Subject: [PATCH 07/10] drm: Store new plane state in a variable for atomic_update and disable
Date: Fri, 15 Jan 2021 13:56:59 +0100
Message-ID: <20210115125703.1315064-7-maxime@cerno.tech> (raw)
In-Reply-To: <20210115125703.1315064-1-maxime@cerno.tech>

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;

 	.atomic_disable = func,
