Hi Bjorn,
Today's linux-next merge of the pci tree got a conflict in
drivers/pci/pci.c between commit c2fb8a3fa255 ("USB: add
NO_D3_DURING_SLEEP flag and revert 151b61284776be2") from Linus' tree and
commit 448bd857d48e ("PCI/PM: add PCIe runtime D3cold support") from the
pci tree.
I fixed it up (I think - see below) and can carry the fix as necessary.
