Subject: linux-next: manual merge of the pm tree with the pci tree

Hi Rafael,

Today's linux-next merge of the pm tree got a conflict in
drivers/pci/pci-acpi.c between commit 181380b702ee ("PCI/ACPI: Don't
cache _PRT, and don't associate them with bus numbers") from the pci tree
and commit bc9b6407bd6d ("ACPI / PM: Rework the handling of devices
depending on power resources") from the pm tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).
