[PATCH 0/9] PCI hotplug diet

[Lukas Wunner]

Here's PCI hotplug material I've prepared for v4.20:

Patches [1/9] to [8/9] reduce the code by 488 lines.  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.

Thanks,

Lukas
