Respin of this series to polish the runtime PM support for PCIe ports
that was added with v4.8, and extend it to native hotplug ports:
- All patches have been reviewed by Rafael, patches 1 to 8 have been
tested by Mika. (Thanks a lot!)
- Patch 6 ("PCI: Unfold conditions to block runtime PM on PCIe ports")
contains a minor change relative to v1 wherein the function returns
as soon as a single condition evaluates to true. (Instead of
needlessly evaluating all the remaining conditions.)
- Patch 9 was rebased to accommodate to this change but is otherwise
the same as before.
As usual I've pushed the series to GitHub to ease reviewing/fetching:
