driver core: remove device_change_owner() export

gregkh · gregkh · commit f55ae0bfa00e · 2026-02-05T16:49:43.000+01:00
The function, device_change_owner() is exported for modules to use, but there are no in-kernel users of it, so remove the export to prevent out-of-tree code from thinking this is a safe function to call.
