[PATCH kernel 0/2] powerpc/powernv: Fix crash on PF unbind when VF is passed

[Alexey Kardashevskiy]

These 2 patches are to fix the crash which happens when the user (accidentally)
unbinds the driver of a physical function of a SRIOV device while
a virtual function is passed to a guest.

Please comment. Thanks!

There might be more work required in addition to this as it is not clear
what protects from races between pnv_ioda_free_pe and pnv_ioda_alloc_pe.
Gavin, please help.

  powerpc/iommu: Get rid of default group_release()
  powerpc/powernv/ioda2: Delay PE disposal
