From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: From: Florian Grandel To: linux-bluetooth@vger.kernel.org Subject: [PATCH v7 05/20] Bluetooth: mgmt: multi adv for read_adv_features() Date: Sat, 13 Jun 2015 05:40:58 +0200 Message-Id: <1434166873-21595-6-git-send-email-fgrandel@gmail.com> In-Reply-To: <1434166873-21595-1-git-send-email-fgrandel@gmail.com> References: <1434166873-21595-1-git-send-email-fgrandel@gmail.com> In-Reply-To: <1432600463-7758-1-git-send-email-fgrandel@gmail.com> References: <1432600463-7758-1-git-send-email-fgrandel@gmail.com> Sender: linux-bluetooth-owner@vger.kernel.org List-ID: The read_adv_features() method had a single instance identifier hard coded. Refer to the advertising instance list instead to return a dynamically generated list of instance identifiers.
