Date: Sun, 9 Feb 2014 20:59:01 -0500 From: Peter Hurley <peter@...leysoftware.com> To: Marcel Holtmann <marcel@...tmann.org> Cc: Gustavo Padovan <gustavo@...ovan.org>, Johan Hedberg <johan.hedberg@...il.com>, Gianluca Anzolin <gianluca@...tospazio.it>, Alexander Holler <holler@...oftware.de>, Andrey Vihrov <andrey.vihrov@...il.com>, Sander Eikelenboom <linux@...elenboom.it>, linux-bluetooth@...r.kernel.org, linux-kernel@...r.kernel.org, Peter Hurley <peter@...leysoftware.com> Subject: [PATCH 01/24] Revert "Bluetooth: Remove rfcomm_carrier_raised()" This reverts commit f86772af6a0f643d3e13eb3f4f9213ae0c333ee4. This is the first of a 3-patch revert, together with Revert "Bluetooth: Always wait for a connection on RFCOMM open()" and Revert "Bluetooth: Move rfcomm_get_device() before rfcomm_dev_activate()". Commit 4a2fb3ecc7467c775b154813861f25a0ddc11aa0, "Bluetooth: Always wait for a connection on RFCOMM open()" open-codes blocking on tty open(), rather than using the default behavior implemented by the tty port. The reasons for reverting that patch are detailed in that changelog; this patch restores required functionality for that revert.
