This is a simple and straight forward cleanup series that makes all device
types in the net subsystem constants. This has been possible since 2011 [1]
but not all occurrences were cleaned. I have been sweeping the tree to fix
them all.

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