From 9f9c10ebe22771d2ff803f39589146aafdda4b23 Mon Sep 17 00:00:00 2001

Subject: [PATCH 5495/5725] drm/amd/display: fix memory leak in resource pools
[why]
ddc engines were recently changed to be independently tracked
from pipe count. the change was reflected in resource constructor
but not in destructor. this manifests as a memory leak when
pipe harvesting is enabled, since not all constructed ddc engines
are freed
[how]
make destructor symmetric with constructor for all dcX_resource
