ACPI / glue: Drop .find_bridge() callback from struct acpi_bus_type
After PCI and USB have stopped using the .find_bridge() callback in struct acpi_bus_type, the only remaining user of it is SATA, but SATA only pretends to be a user, because it points that callback to a stub always returning -ENODEV. For this reason, drop the SATA's dummy .find_bridge() callback and remove .find_bridge(), which is not used any more, from struct acpi_bus_type entirely. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Acked-by: Yinghai Lu <yinghai@kernel.org> Acked-by: Jeff Garzik <jgarzik@pobox.com>
