Wysocki In order to avoid exposing acpi_bus_type to modules, introduce an acpi_bus_for_each_dev() helper for iterating over all ACPI device objects and make typec_link_ports() use it instead of the raw bus_for_each_dev() along with acpi_bus_type. Having done that, drop the acpi_bus_type export. No intentional functional impact. Signed-off-by: Rafael J.
