[Qemu-devel] [PULL 02/11] pci_bridge: manually destroy memory regions within PCIBridgeWindows

[Michael S. Tsirkin]

From: Paolo Bonzini <pbonz...@redhat.com>

The regions are destroyed and recreated on configuration space accesses.
We need to destroy them before the containing PCIBridgeWindows object
is freed.
