Return-Path: From: Andre Guedes To: linux-bluetooth@vger.kernel.org Subject: [PATCH 2/3] Bluetooth: mgmt_stop_discovery_failed() Date: Wed, 9 Nov 2011 17:14:26 -0300 Message-Id: <1320869667-1373-2-git-send-email-andre.guedes@openbossa.org> In-Reply-To: <1320869667-1373-1-git-send-email-andre.guedes@openbossa.org> References: <1320869667-1373-1-git-send-email-andre.guedes@openbossa.org> Sender: linux-bluetooth-owner@vger.kernel.org List-ID: This patches creates mgmt_stop_discovery_failed() which removes pending MGMT_OP_STOP_DISCOVERY commands and sends proper command status events. This patch also fixes the MGMT_OP_STOP_DISCOVERY command leak in case cancel inquiry fails.
