Subject: drm/amdgpu: Use drm_dev_unplug in PCI .remove
X-Git-Tag: v5.4-rc1~2273^2~27^2~157

drm/amdgpu: Use drm_dev_unplug in PCI .remove

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.
