From 3a7dbfb8ff943711be4221df978254ad2bc1ac46 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Wed, 10 Sep 2014 17:37:41 -0700 Subject: [PATCH] Bluetooth: Remove unnecessary early initialization of variable We do nothing else with the auth variable in smp_cmd_pairing_rsp() besides passing it to tk_request() which in turn only cares about whether one of the sides had the MITM bit set. It is therefore unnecessary to assign a value to it until just before calling tk_request(), and this value can simply be the bit-wise or of the local and remote requirements.
