[PATCH v14.c 2/4] PCI: ACPI: Consider non-hotplug bridges for D3 in acpi_pci_bridge_d3()

From: Mario Limonciello
Date: Fri Aug 18 2023 - 15:41:53 EST


acpi_pci_bridge_d3() only runs on hotplug bridges. Two checks are made
for _S0W and for whether a device is power manageable contingent upon
an ACPI companion being present.

These checks also make sense for non-hotplug bridges, so move the
check for hotplug bridge after the acpi companion checks.
