From 7be2edbbb87a34fbf1441991a679af94fe1d981d Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Sun, 23 Feb 2014 19:42:17 +0200 Subject: [PATCH] Bluetooth: Ensure hci_conn always contains the local identity address To be consistent with the remote address info in hci_conn we want it to also contain the local identity address information. This patch updates the code to copy the right values in place whenever an LE connection has been established.
