From: Johan Hedberg Date: Sun, 23 Feb 2014 17:42:17 +0000 (+0200) Subject: Bluetooth: Ensure hci_conn always contains the local identity address X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7be2edbbb87a34fbf1441991a679af94fe1d981d;p=linux-beck.git 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.
