Return-Path: From: Florian Grandel To: linux-bluetooth@vger.kernel.org Subject: [PATCH v4 11/17] Bluetooth: mgmt: multi adv for create_instance_adv_data() Date: Thu, 30 Apr 2015 17:33:14 +0200 Message-Id: <1430408000-17785-12-git-send-email-fgrandel@gmail.com> In-Reply-To: <1430408000-17785-1-git-send-email-fgrandel@gmail.com> References: <1430408000-17785-1-git-send-email-fgrandel@gmail.com> In-Reply-To: <1428633041-18415-1-git-send-email-fgrandel@gmail.com> References: <1428633041-18415-1-git-send-email-fgrandel@gmail.com> Sender: linux-bluetooth-owner@vger.kernel.org List-ID: The create_instance_adv_data() function could not deal with multiple advertising instances previously. This is being fixed by retrieving advertising instances from the newly introduced dynamic advertising instance list.
