Merge tag 'vfio-v6.6-rc4' of https://github.com/awilliam/linux-vfio
Pull VFIO fixes from Alex Williamson:
- The new PDS vfio-pci variant driver only supports SR-IOV VF devices
and incorrectly made a direct reference to the physfn field of the
pci_dev. Fix this both by making the Kconfig depend on IOV support
as well as using the correct wrapper for this access (Shixiong Ou)
- Resolve an error path issue where on unwind of the mdev registration
the created kset is not unregistered and the wrong error code is
returned (Jinjie Ruan)
