Subject: Bluetooth: Change signature of smp_conn_security()
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=cc110922da7e902b62d18641a370fec01a9fa794;p=openwrt%2Fstaging%2Fblogic.git

Bluetooth: Change signature of smp_conn_security()

To make it clear that it may be called from contexts that may not have
any knowledge of L2CAP, we change the connection parameter, to receive
a hci_conn.

This also makes it clear that it is checking the security of the link.
