Thanks!

No need to do mass-conversions to __maybe_unused though, 
Kirtika Ruchandani has started working on a way for the suspend/resume
functions to automatically get silently discarded when they are
unused, without having an #ifdef or __maybe_unused annotation.

For new code, using __maybe_unused helps avoid this bug though,
and the conversion to the future macros would be easy enough.
