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.
