From f18e29fc90cf271bae0c671151d0f55bd7649d52 Mon Sep 17 00:00:00 2001 From: Igor Mammedov Date: Thu, 2 Mar 2023 17:15:43 +0100 Subject: pcihp: add ACPI PCI hotplug specific is_hotpluggable_bus() callback Provide pcihp specific callback to check if bus is hotpluggable and consolidate its scattered hotplug criteria there. While at it clean up no longer needed qbus_set_hotplug_handler(BUS(bus), NULL) workarounds since callback makes qbus_is_hotpluggable() return correct answer even if hotplug_handler is set on bus. PS: see ("pci: fix 'hotplugglable' property behavior") for details why callback was introduced.
