[PATCH v4 0/4] Move vfio_ccw to the new mdev API

[Jason Gunthorpe <jgg@nvidia.com>]

This is the first 4 patches of the v3 series which only change CCW to use
the new VFIO API for mdevs and leaves the lifetime model as-is.

As agreed, we will go ahead with this set and IBM can take the remaining
patches of cleanup when they want. (I won't resend them)

Alex: as Eric has now ack'd them please take them to the VFIO tree for
this upcoming merge window

This is on github: https://github.com/jgunthorpe/linux/commits/vfio_ccw

Thanks,
Jason
