From 07e307f807fecf056f0f9024ade4c0187159c46b Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Wed, 16 Oct 2013 11:37:00 +0300 Subject: [PATCH] Bluetooth: Ignore A2MP data on non-BR/EDR links The A2MP CID is only valid for BR/EDR transports. We should ignore A2MP data on non-BR/EDR links and refuse to create an amp_mgr object.
