  vfio/mdev: Fix a null-ptr-deref bug for mdev_unregister_parent() (2023-09-22 12:48:04 -0600)

VFIO fixes for v6.6-rc4

 - 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)
