From 2827011f666e157f3307d55070a75e1d1110b194 Mon Sep 17 00:00:00 2001 From: Mat Martineau Date: Thu, 17 May 2012 21:14:09 -0700 Subject: Bluetooth: Fix early return from l2cap_chan_del This fixes a regression from commit 2ead70b8390d199ca04cd35311b51f5f3676079e that is present in all kernels starting at v3.0. When L2CAP information was moved to struct l2cap_chan, a check was added to l2cap_chan_del to avoid certain cleanup operations when ERTM or streaming mode had not yet been initialized. The logic in the check did not take in to account that chan->conf_state is set to 0 in l2cap_chan_ready, so l2cap_chan_del failed to cancel timers and leaked memory any time the ERTM queues or lists were not empty. This change makes sure that l2cap_chan_del only returns early if ERTM initialization was not performed.
