Subject: Bluetooth: btusb: Remove device lock on release
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=9ab875affbe61b2c88685c342461c9a367ab7a3e;p=linux-beck.git

Bluetooth: btusb: Remove device lock on release

Recently we changed the way how we release driver-data. A driver is now
responsible of destroying the data so we no longer need the device lock
on deinitialization in btusb driver.
