From e72acc13c770a82b4ce4a07e9716f29320eae0f8 Mon Sep 17 00:00:00 2001 From: Andre Guedes Date: Fri, 27 Jan 2012 19:42:03 -0300 Subject: [PATCH] Bluetooth: Remove unneeded locking We don't need locking hdev in hci_conn_timeout() since it doesn't access any hdev's shared resources, it basically queues HCI commands.
