Two problems have been discovered with the vfio_ap device driver since the
hot plug support was recently introduced:

1. Attempting to remove a matrix mdev after assigning a duplicate adapter
or duplicate domain results in a hang.

2. The queues associated with an adapter or domain being unassigned from
the matrix mdev do not get unlinked from it.

Two patches are provided to resolve these problems.

Tony Krowiak (2):
s390/vfio-ap: fix hang during removal of mdev after duplicate
assignment
s390/vfio-ap: fix unlinking of queues from the mdev
