From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: From: Marcel Holtmann To: linux-bluetooth@vger.kernel.org Subject: [PATCH] Bluetooth: Fix HCIUARTGETDEVICE ioctl when UART is not registered Date: Sat, 12 Jul 2014 17:00:29 +0200 Message-Id: <1405177229-13849-1-git-send-email-marcel@holtmann.org> Sender: linux-bluetooth-owner@vger.kernel.org List-ID: The protocol for the UART might be configured, but that does not mean the HCI device is registered. Return an error in that case and only return the index number when HCI_UART_REGISTERED is set.
