[PATCHv4 0/3] pci slot reset handling fixes

[Keith Busch <kbusch@meta.com>]

From: Keith Busch <kbusch@kernel.org>

Changes from previous version:

 * Dropped the patch that unifies bus and slot reset device locking and
   config space restoration. There were good intentions for proposing
   it, but it's not necessary anymore for the pciehp case at hand and
   it introduces risks by conflating what is actually affected when you
   request a slot reset.

 * Fixed up some typos, added requested code comments

 * Fixed up the compilation linking mistake in patch 1

 * I changed a parameter name in the last patch for the common bridge
   reset method. Previously called "masked", but it's really the case
   that both methods want to mask hotplug events. The real difference
   between thw two options is whether we save+restore the affected
   devices. The error handling path doesn't want that because the error
   handler is responsible for it. But everyone else wants the reset
   handler to take care of it automatically.

 * Added reviews

Keith Busch (3):
  pci: rename __pci_bus_reset and __pci_slot_reset
  pci: allow all bus devices to use the same slot
  pci: make reset_subordinate hotplug safe
