Yup, the function description also needs fixing:

@@ -260,11 +260,11 @@ int selinux_netlbl_skbuff_setsid(struct sk_buff *skb,

 /**
  * selinux_netlbl_sctp_assoc_request - Label an incoming sctp association.
- * @ep: incoming association endpoint.
+ * @asoc: incoming association.
  * @skb: the packet.
  *
  * Description:
- * A new incoming connection is represented by @ep, ......
+ * A new incoming connection is represented by @asoc, ......
  * Returns zero on success, negative values on failure.
