There should be no loss of functionality and no new features, just less and simpler code. Patch [9/9] collects TODOs for hotplug drivers to spur contributions. I've assumed that my patch "PCI: pciehp: Differentiate between surprise and safe removal" (submitted July 31) gets merged before this series: https://patchwork.ozlabs.org/patch/951386/ If that patch is not accepted or other pciehp-related patches are merged before this series, I'll have to rebase patch [4/9] ("PCI: pciehp: Unify controller and slot structs"). No big deal, just a heads-up.
