From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx>
Since _handle_hotplug_event_root() is run from the ACPI hotplug
workqueue, it doesn't need to queue up a work item to eject a PCI
host bridge on the same workqueue. Instead, it can just carry out
the eject by calling acpi_bus_device_eject() directly, so make that
happen.
