[ Upstream commit f423fa1bc9fe1978e6b9f54927411b62cb43eb04 ] |
| 9 |
|
| 10 |
When converting to directly create the vfio_device the mdev driver has to |
| 11 |
put a vfio_register_emulated_iommu_dev() in the probe() and a pairing |
| 12 |
vfio_unregister_group_dev() in the remove. |
| 13 |
|
| 14 |
This was missed for gvt, add it. |
