- Set power state to 'unknown' for all devices, not just those with
  drivers, during suspend (Lukas Wunner)

- Skip restoring Resizable BARs and VF Resizable BARs if device doesn't
  respond to config reads, to avoid invalid array accesses (Marco
  Nenciarini)

- Add pci_suspend_retains_context() so drivers can tell whether devices may
  be reset while resuming from suspend due to platform issues; use this in
  nvme to avoid issues on Qcom RCs (Manivannan Sadhasivam)

* pci/pm:
  nvme-pci: Use pci_suspend_retains_context() during suspend
  PCI: qcom: Indicate broken L1SS exit during resume from system suspend
  PCI: Indicate context lost if L1SS exit is broken during resume from system suspend
  PCI: Add pci_suspend_retains_context() to check if device state is preserved during suspend
  PCI/IOV: Skip VF Resizable BAR restore on read error
  PCI: Skip Resizable BAR restore on read error
  PCI: Stop setting cached power state to 'unknown' on unbind
