The function cdn_dp_resume() may have no callers depending
on configuration, so it must be marked __maybe_unused to
avoid harmless warning:
drivers/gpu/drm/rockchip/cdn-dp-core.c:1124:12: warning:
'cdn_dp_resume' defined but not used [-Wunused-function]
1124 | static int cdn_dp_resume(struct device *dev)
