Technical Description
In the Linux kernel, the following vulnerability has been resolved:
drm/i915/gvt: fix vgpu debugfs clean in remove
Check carefully on root debugfs available when destroying vgpu,
e.g in remove case drm minor's debugfs root might already be destroyed,
which led to kernel oops like below.
Console: switching to colour dummy device 80x25
