From b9dc4e04c807ad3860a9ba8773b3b0e7057c31aa Mon Sep 17 00:00:00 2001 From: Eric Auger Date: Mon, 14 Jul 2025 10:04:59 +0200 Subject: [PATCH] hw/i386/acpi-build: Use AcpiPciHpState::root in acpi_set_pci_info pcihp acpi_set_pci_info() generic code currently uses acpi_get_i386_pci_host() to retrieve the pci host bridge. To make it work also on ARM we get rid of that call and directly use AcpiPciHpState::root.
