randstruct: Whitelist struct security_hook_heads cast
The LSM initialization routines walk security_hook_heads as an array of struct list_head instead of via names to avoid a ton of needless source. Whitelist this to avoid the false positive warning from the plugin: security/security.c: In function ‘security_init’: security/security.c:59:20: note: found mismatched op0 struct pointer types: ‘struct list_head’ and ‘struct security_hook_heads’ struct list_head *list = (struct list_head *) &security_hook_heads; ^ Cc: Tetsuo Handa <penguin-kernel@I-love.SAKURA.ne.jp> Cc: James Morris <james.l.morris@oracle.com> Signed-off-by: Kees Cook <keescook@chromium.org>
