From cf70ff220a918b25d383510f913de52308d04bb2 Mon Sep 17 00:00:00 2001 From: Andrei Emeltchenko Date: Wed, 31 Oct 2012 15:46:36 +0200 Subject: [PATCH] Bluetooth: AMP: Use l2cap_physical_cfm in phylink complete evt When receiving HCI Phylink Complete event run amp_physical_cfm which initialize BR/EDR L2CAP channel associated with High Speed link and run l2cap_physical_cfm which shall send L2CAP Create Chan Request.
