From f706f6483e6edac051d20ef50f3c8dbf4b674a7c Mon Sep 17 00:00:00 2001

Subject: [PATCH 0317/2940] 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.
