From 974e6b641f1428ee14486da277a92bdf9bd04a78 Mon Sep 17 00:00:00 2001

Subject: [PATCH 0300/1050] drm/amdgpu: disable the IP module if early_init
returns -ENOENT (v2)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
If we run into a part with a harvest configuration where the entire
IP block is unusable, just disable the IP block.
v2: fix logic as noted by Christian
