3.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johan Hedberg <johan.hedb...@intel.com>
commit 9eb1fbfa0a737fd4d3a6d12d71c5ea9af622b887 upstream.
Commit 1c2e004183178 introduced an event handler for the encryption key
refresh complete event with the intent of fixing some LE/SMP cases.
However, this event is shared with BR/EDR and there we actually want to
act only on the auth_complete event (which comes after the key refresh).
If we do not do this we may trigger an L2CAP Connect Request too early
and cause the remote side to return a security block error.
