From 6e792a90dee712edbbdf20f102c76bb9b8e36598 Mon Sep 17 00:00:00 2001 From: Vinicius Costa Gomes Date: Thu, 23 Aug 2012 21:32:43 -0300 Subject: [PATCH] Bluetooth: Change signature of smp_conn_security() commit cc110922da7e902b62d18641a370fec01a9fa794 upstream. To make it clear that it may be called from contexts that may not have any knowledge of L2CAP, we change the connection parameter, to receive a hci_conn. This also makes it clear that it is checking the security of the link.
