Subject: [PATCH RESEND] Bluetooth: btbcm: Add default address for BCM2076B1
Date: Wed,  1 May 2019 09:18:23 +0200	[thread overview]
Message-ID: <20190501071820.6404-1-stephan@gerhold.net> (raw)
In-Reply-To: <863F9BB0-25C7-4A9B-8D91-2A2D2690D13D@holtmann.org>

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.
