Subject: drm/amdgpu: fix unload driver fail
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=c8bdf2b63e5b6b31b3b4826b8e87c0c2f6b650ff;p=openwrt%2Fstaging%2Fblogic.git

drm/amdgpu: fix unload driver fail

dc_destroy should be called amdgpu_cgs_destroy_device,
as it will use cgs context to read or write registers.
