When building using a riscv allmodconfig the following build warning is
seen:
drivers/gpu/drm/rockchip/cdn-dp-core.c:1124:12: warning: 'cdn_dp_resume' defined but not used [-Wunused-function]
Pass __maybe_unused for the suspend()/resume() hooks to fix the build
warning when a defconfig does not select CONFIG_PM_SLEEP.
Reported-by: Olof's autobuilder <build@xxxxxxxxx>
