[Brett Creeley]

This series contains fixes for locking bugs in the recently introduced
pds-vfio-pci driver. There was an initial bug reported by Dan Carpenter
at:

https://lore.kernel.org/kvm/1f9bc27b-3de9-4891-9687-ba2820c1b390@moroto.mountain/

However, more locking bugs were found when looking into the previously
mentioned issue. So, all fixes are included in this series.
