Subject: [PATCH 0/2] drm/i915/gvt: Fix for KVM refcounting bug

Bug fix and cleanup related to KVM refcounting. Found by inspection while
attempting to clean up KVM's page-tracker APIs.

Compile tested only!

Sean Christopherson (2):
drm/i915/gvt: Get reference to KVM iff attachment to VM is successful
drm/i915/gvt: Unconditionally put reference to KVM when detaching vGPU
