From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com> When receiving a Open command the stream will be set as pending_open but the remote may attempt to send yet another Open command in the meantime reseting resulting in another setup and yet another timer leaving the old timer active which will likely cause a crash when it expires. --- profiles/audio/avdtp.c | 10 ++++++---- 1 file changed, 6 insertions(+), 4 deletions(-)
