From 4185a0f5d0431bf91ea1ec202fdf12e6e3b73c46 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Mon, 6 Apr 2015 00:52:12 -0700 Subject: [PATCH] Bluetooth: btusb: Use generic Intel support for address support The Bluetooth address handling for Intel devices is provided by a generic module now. Start using that module instead of relying it being included in the driver.
