After a5bf8719af: "PCI/AER: Use only _OSC to determine AER ownership", _OSC is the primary determiner of ownership of Firmware First error handling rather than HEST. ACPI Root Bus enumeration has been modified to flag Host Bridge devices as using Native AER when _OSC has been negotiated for AER services. This patch ensures the PCI layers first uses the _OSC negotiated state by checking the Host Bridge's Native AER flag prior to HEST parsing.
