Subject: Bluetooth: Fix old_key_type logic for non-persistent keys
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=12adcf3a953c3aa4006d855aa638133bf018ceac;p=mv-sheeva.git

Bluetooth: Fix old_key_type logic for non-persistent keys

Even if there's no previous key stored the connection might still be
secured with a non-persistent key and in that case the key type in the
hci_conn struct should be checked.
