Mark these functions as __maybe_unused, which is the standard procedure for
PM functions.

Thank you for the review :)
These warnings were introduced by a patch in this merge window, it would
be nice if this patch could be fixed up as a fix for that but I
understand if it is too late for that.
Cheers,
Nathan
