From 567fa2aa3dfad9848c25a226927a4ca5f94229ac Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Tue, 24 Jun 2014 13:15:48 +0300 Subject: [PATCH] Bluetooth: Update hci_add_link_key() to return pointer to key By returning the added (or updated) key we pave the way for further refactoring (in subsequent patches) that allows moving the mgmt event sending out from this function (and thereby removal of the awkward new_key parameter).
