Subject: [PATCH v1 2/3] ACPI: glue: Drop cleanup callback from struct acpi_bus_type

From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>

Since PCI was the only user of the ->cleanup callback in struct
acpi_bus_type and it is not using struct acpi_bus_type any more,
drop that callback from there and update acpi_device_notify_remove()
accordingly.
