Return-Path: From: Andre Guedes To: linux-bluetooth@vger.kernel.org Subject: [PATCH v2 01/17] Bluetooth: Create hci_req_add_le_scan_disable helper Date: Wed, 26 Feb 2014 20:21:40 -0300 Message-Id: <1393456916-22701-1-git-send-email-andre.guedes@openbossa.org> Sender: linux-bluetooth-owner@vger.kernel.org List-ID: This patch moves stop LE scanning duplicate code to one single place and reuses it. This will avoid more duplicate code in upcoming patches.
