From 300926b138eb30ce1763d1d10604230d4d38d64a Mon Sep 17 00:00:00 2001 From: Stephan Gerhold Date: Wed, 1 May 2019 09:18:23 +0200 Subject: [PATCH] Bluetooth: btbcm: Add default address for BCM2076B1 BCM2076B1 appears to use 20:76:A0:00:56:79 as default address. This address is used by at least 5 devices with the AMPAK AP6476 module and is also suspicious because it starts with the chip name 2076 (followed by a different revision A0 for some reason). Add it to the list of default addresses and leave it up to the user to configure a valid one.
