Here's a v2 of this patch series which is being sent, because I realized that one of the checks in pci_power_up() added by patch [4/7] in v1 was redundant and can be dropped, but that affected the last 3 patches in the series and then I noticed that more improvements were possible and hence the new patches [2/9].
