From 4d6c705bbd9e845bcfbe119bb017a5653c0d9efb Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Sun, 13 Jul 2014 00:29:22 +0200 Subject: [PATCH] Bluetooth: Enable LE Long Term Key Request event only when supported The support for LE encryption is optional and with that also the LE Long Term Key Request event. If encryption is not supported, then do not bother enabling this event.
