[PATCH] Bluetooth: constify the struct device_type usage

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


Since commit aed65af1cc2f ("drivers: make device_type const"), the driver
core can properly handle constant struct device_type. Move the bt_type and
bnep_type variables to be constant structures as well, placing it into
read-only memory which can not be modified at runtime.
