Merge branch 'pci/enumeration'

Browse source 
- Don't store pci_device_id in agp amd-k7 and via, ata, scsi nsp32, ipack
  tpci200, mlxsw since the dynamic ID feature means the ID is only
  guaranteed to live during probe (Gary Guo)

- Add pci_match_one_id() to match an ID directly so dynamic ID insertion
  doesn't need to make a temporary device for matching (Gary Guo)

- Check for existing ID inside the dynamic ID addition critical section to
  avoid a time-of-check vs time-of-use race (Gary Guo)

- Copy device ID to avoid use-after-free when match races with sysfs
  dynamic ID removal (Gary Guo)

* pci/enumeration:
  PCI: Fix UAF when probe runs concurrent to dyn ID removal
  PCI: Fix dyn_id add TOCTOU
  PCI: Make pci_match_one_device() match on ID instead of device
  agp/amd-k7: Don't rely on address of pci_device_id
  agp/via: Don't rely on address of pci_device_id
  mlxsw: pci: Don't store pci_device_id
  ipack: tpci200: Don't store pci_device_id
  scsi: nsp32: Don't store pci_device_id
