Pull IOMMU fix from Joerg Roedel:
 "Another fix, this time in common IOMMU sysfs code.

  In the conversion from the old iommu sysfs-code to the
  iommu_device_register interface, I missed to update the release path
  for the struct device associated with an IOMMU. It freed the 'struct
  device', which was a pointer before, but is now embedded in another
  struct.

  Freeing from the middle of allocated memory had all kinds of nasty
  side effects when an IOMMU was unplugged. Unfortunatly nobody
  unplugged and IOMMU until now, so this was not discovered earlier. The
  fix is to make the 'struct device' a pointer again"
