I chose the current stubs approach based on existing examples like
hw_timestamps. Any implementation, including the current one, will have
zero kernel size impact because each function is only used once. While
moving them to a C source file is an option, it doesn't seem necessary
given the current usage pattern. Do we really want to spend more time on
this for something that won’t impact functionality or size? :)
