What tree do you plan to take it through?

Lets see.. These were already applied:

  vfio/ccw: Remove unneeded GFP_DMA
  vfio/ccw: Use functions for alloc/free of the vfio_ccw_private
  vfio/ccw: Pass vfio_ccw_private not mdev_device to various functions
  vfio/ccw: Convert to use vfio_register_emulated_iommu_dev()

This series replaces this one:
  vfio/ccw: Make the FSM complete and synchronize it to the mdev

Christoph recently re-posted this:
https://lore.kernel.org/kvm/20220628051435.695540-10-hch@lst.de/
  vfio/mdev: Consolidate all the device_api sysfs into the core code

So this is still left ?
  vfio/ccw: Remove private->mdev
  vfio: Export vfio_device_try_get()
  vfio/ccw: Move the lifecycle of the struct vfio_ccw_private to the
    mdev

IIRC Kevin's team needs those for their device FD patches?

Thanks,
Jason
