Subject: [PATCH 3.12 091/170] Bluetooth: Allow change security level on ATT_CID in slave role

From: Marcin Kraglak <marcin.kraglak@...to.com>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit 92d1372e1a9fec00e146b74e8b9ad7a385b9b37f upstream.

Kernel supports SMP Security Request so don't block increasing security
when we are slave.
