There are two fields in struct acpi_device_pnp, device_name and device_class, that were supposed to be populated and used by device drivers, but they have never been used consistently and now they are only set for the bus object in acpi_set_pnp_ids() (and never read afterward). Drop them along with all of the associated symbols except for MAX_ACPI_CLASS_NAME_LEN and the acpi_device_class typedef that are used by the ACPI netlink messaging code. Move those two definitions closer to the struct acpi_bus_event that refers to the acpi_device_class type. No intentional functional impact. Signed-off-by: Rafael J.
