Merge branch 'pci/enumeration'
- Probe bridge window attributes only once at enumeration-time to fix
device accesses during rescan (Bjorn Helgaas)
- Return BAR size (not "size -1 ") from pci_size() to simplify code (Du
Changbin)
- Use config header type (not class code) identify bridges more reliably
(Honghui Zhang)
- Work around Intel Denverton incorrect Trace Hub BAR size reporting
(Alexander Shishkin)
* pci/enumeration:
x86/PCI: Fixup RTIT_BAR of Intel Denverton Trace Hub
PCI: Rely on config space header type, not class code
PCI: Make pci_size() return real BAR size
PCI: Probe bridge window attributes once at enumeration-time
