RE: [PATCH] drm/i915/gvt: Add missing vfio_unregister_group_dev() call

From: Jason Gunthorpe Sent: Friday, September 30, 2022 1:49 AM

When converting to directly create the vfio_device the mdev driver has to put a vfio_register_emulated_iommu_dev() in the probe() and a pairing vfio_unregister_group_dev() in the remove.

This was missed for gvt, add it.
