  kvm/vfio: Fix potential deadlock on vfio group_lock (2023-01-20 08:50:05 -0700)

VFIO fixes for v6.2-rc6

 - Honor reserved regions when testing for IOMMU find grained super
   page support, avoiding a regression on s390 for a firmware device
   where the existence of the mapping, even if unused can trigger
   an error state. (Niklas Schnelle)

 - Fix a deadlock in releasing KVM references by using the alternate
   .release() rather than .destroy() callback for the kvm-vfio device.
   (Yi Liu)
