From b7165ebbf0898bad9aaeddfa22b918e94ed90e07 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Thu, 6 Jun 2013 13:52:19 -0700 Subject: kobject: sanitize argument for format string Unlike kobject_set_name(), the kset_create_and_add() interface does not provide a way to use format strings, so make sure that the interface cannot be abused accidentally. It looks like all current callers use static strings, so there's no existing flaw.
