      drm/i915/gvt: Change KVMGT as self load module · 9bdb0734
      Zhenyu Wang authored
      This trys to make 'kvmgt' module as self loadable instead of loading
      by i915/gvt device model. So hypervisor specific module could be
      stand-alone, e.g only after loading hypervisor specific module, GVT
      feature could be enabled via specific hypervisor interface, e.g VFIO/mdev.
      
      So this trys to use hypervisor module register/unregister interface
      for that. Hypervisor module needs to take care of module reference
      itself when working for hypervisor interface, e.g for VFIO/mdev,
      hypervisor module would reference counting mdev when open and release.
      
      This makes 'kvmgt' module really split from GVT device model. User
      needs to load 'kvmgt' to enable VFIO/mdev interface.
      
      v6:
      - remove unused variable
      
      v5:
      - put module reference in register error path
      
      v4:
      - fix checkpatch warning
      
      v3:
      - Fix module reference handling for device open and release. Unused
        mdev devices would be cleaned up in device unregister when module unload.
      
      v2:
      - Fix kvmgt order after i915 for built-in case
