From 597258e5effb6ab56a116823e8cb88ccc578ec06 Mon Sep 17 00:00:00 2001

Subject: [PATCH] drm/vc4: plane: Register a different
drm_plane_helper_funcs on BCM2711
On the BCM2711, our current definition of drm_plane_helper_funcs uses
the custom vc4_prepare_fb() and vc4_cleanup_fb().
Those functions rely on the buffer allocation path that was relying on
the GPU, and is no longer relevant.
Let's create another drm_plane_helper_funcs structure that we will
register on the BCM2711.
