[PATCH 09/14] Bluetooth: btusb: Use generic functionality by Broadcom module

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The new Broadcom Bluetooth support module provides generic functionality
for changing and checking the Bluetooth device address. Use these new
features instead of keeping a duplicate in the driver.
