From 03a001948166d966d0d580cddb8ae3a23f8b795b Mon Sep 17 00:00:00 2001 From: "Gustavo F. Padovan" Date: Fri, 9 Dec 2011 04:48:17 -0200 Subject: Bluetooth: invert locking order in connect path This move some checking code that was in l2cap_sock_connect() to l2cap_chan_connect(). Thus we can invert the lock calls, i.e., call lock_sock() before hci_dev_lock() to avoid a deadlock scenario. Acked-by: Marcel Holtmann Signed-off-by: Gustavo F.
