When CONFIG_PM is disabled, we get harmless warnings about the suspend/resume callbacks being unused: drivers/media/pci/intel/ipu3/ipu3-cio2.c:1993:12: error: 'cio2_resume' defined but not used [-Werror=unused-function] drivers/media/pci/intel/ipu3/ipu3-cio2.c:1967:12: error: 'cio2_suspend' defined but not used [-Werror=unused-function] This marks them as __maybe_unused to shut up the warnings.
