From acea6852f32b8805e166d885ed7e9f0c7cd10d41 Mon Sep 17 00:00:00 2001 From: Dave Young Date: Mon, 21 Jan 2008 22:35:21 -0800 Subject: [BLUETOOTH]: Move children of connection device to NULL before connection down. The rfcomm tty device will possibly retain even when conn is down, and sysfs doesn't support zombie device moving, so this patch move the tty device before conn device is destroyed.
