Return-Path: From: Johan Hedberg To: linux-bluetooth@vger.kernel.org Subject: [PATCH v4 19/26] Bluetooth: Refactor fast connectable HCI commands Date: Wed, 13 Mar 2013 11:12:10 -0700 Message-Id: <1363198337-3896-20-git-send-email-johan.hedberg@gmail.com> In-Reply-To: <1363198337-3896-1-git-send-email-johan.hedberg@gmail.com> References: <1363198337-3896-1-git-send-email-johan.hedberg@gmail.com> Sender: linux-bluetooth-owner@vger.kernel.org List-ID: From: Johan Hedberg This patch refactors the fast connectable HCI commands into their own HCI function. This is necessary so that the same function can be reused fo the fast connectable change required by disabling the connectable setting.
