Hi all,

After merging the drm-intel-fixes tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/gpu/drm/i915/gvt/kvmgt.c: In function 'intel_vgpu_open':
drivers/gpu/drm/i915/gvt/kvmgt.c:511:32: error: dereferencing pointer to incomplete type 'struct mdev_device'
  vfio_unregister_notifier(&mdev->dev, VFIO_GROUP_NOTIFY,
                                ^   

Caused by commit

  99e3123e3d72 ("vfio-mdev: Make mdev_device private and abstract interfaces")

from the vfio-fixes tree interacting with commit

  364fb6b789ff ("drm/i915/gvt/kvmgt: prevent double-release of vgpu")

from the drm-intel-fixes tree.

I applied this merge fix patch:

Subject: [PATCH] vfio-mdev: fixup for "Make mdev_device private and abstract interfaces"
