Thanks a lot - I actually realized that there was a third one, but
blindly assumed that the other patch addressed that (for which the
original broken commit e06670c5fe3b ("s390: vfio-ap: implement
VFIO_DEVICE_GET_INFO ioctl") got an amazing number of eight tags ;))
I'll keep your patch as a seperate one, since it fixes a different
upstream patch.
