I'd prefer it if we didn't change this but only added __maybe_unused in 
the macro.

This is 2013/2014 legacy stuff, some parts were not upstreamed and this 
was used by out-of-tree Android variations, and I don't know the 
consequences of taking this out.

Better just squelch the warning but not change anything, no?
