From aec4486d6889afcfe706684f2d24cfe9350168b4 Mon Sep 17 00:00:00 2001
From: Maxime Ripard <maxime@cerno.tech>
Date: Wed, 23 Nov 2022 16:25:53 +0100
Subject: [PATCH] drm/vc4: Constify container_of wrappers
None of our wrappers around container_of to access our objects from the
DRM object pointer actually modify the latter.
Let's make them const.
