[Qemu-devel] [PULL 1/5] hw/pcie: fix Extended Configuration Space for devices with no Extended Capabilities

[Michael S. Tsirkin]

From: Marcel Apfelbaum <marcel@redhat.com>

Absence of any Extended Capabilities is required to be
indicated by an Extended Capability header with a Capability ID of
0000h, a Capability Version of 0h, and a Next Capability Offset of 000h.

Instead of inserting a 'NULL' capability is simpler to mark the start
of the Extended Configuration Space as read-only to achieve the same
behaviour.

This has an incorrect submodule revert in it, and I missed it before
