  vfio: Drop vfio_file_iommu_group() stub to fudge around a KVM wart (2023-11-30 11:27:17 -0700)

----------------------------------------------------------------
VFIO fixes for v6.7-rc4

 - Fix the lifecycle of a mutex in the pds variant driver such that
   a reset prior to opening the device won't find it uninitialized.
   Implement the release path to symmetrically destroy the mutex.
   Also switch a different lock from spinlock to mutex as the code
   path has the potential to sleep and doesn't need the spinlock
   context otherwise. (Brett Creeley)

 - Fix an issue detected via randconfig where KVM tries to symbol_get
   an undeclared function.  The symbol is temporarily declared
   unconditionally here, which resolves the problem and avoids churn
   relative to a series pending for the next merge window which
   resolves some of this symbol ugliness, but also fixes Kconfig
   dependencies. (Sean Christopherson)

----------------------------------------------------------------

      vfio/pds: Fix mutex lock->magic != lock warning
      vfio/pds: Fix possible sleep while in atomic context
