Return-Path: From: Vinicius Costa Gomes To: linux-bluetooth@vger.kernel.org Cc: Vinicius Costa Gomes Subject: [PATCH 1/2] Bluetooth: Change signature of smp_conn_security() Date: Thu, 23 Aug 2012 21:32:43 -0300 Message-Id: <1345768364-9546-1-git-send-email-vinicius.gomes@openbossa.org> Sender: linux-bluetooth-owner@vger.kernel.org List-ID: 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.
