From 7128b6f79f79f0c075c91c53ba6dd1d1a3b05c8e Mon Sep 17 00:00:00 2001
From: Andrey Grodzovsky <andrey.grodzovsky@amd.com>

Subject: [PATCH 5345/5725] drm/amdgpu: Use drm_dev_unplug in PCI .remove
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This at least allows to fail any subsequent IOCTLs with -ENODEV
after the device is gone.
Still this operation is not supported yet in graphic mode
and will lead at least to page faults and other issues.
