If anyone has any objections, please let me know. ------------------ From: Johan Hedberg 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.
