Return-Path: From: Andre Guedes To: linux-bluetooth@vger.kernel.org Subject: [RFC 1/4] Bluetooth: Connection parameters check helper Date: Wed, 25 Jun 2014 16:48:27 -0300 Message-Id: <1403725710-29750-2-git-send-email-andre.guedes@openbossa.org> In-Reply-To: <1403725710-29750-1-git-send-email-andre.guedes@openbossa.org> References: <1403725710-29750-1-git-send-email-andre.guedes@openbossa.org> Sender: linux-bluetooth-owner@vger.kernel.org List-ID: This patch renames l2cap_check_conn_param() to hci_check_conn_params() and moves it to hci_core.h so it can reused in others files. This helper will be reused in the next patch.
