media: ov5695: mark PM functions as __maybe_unused
Without CONFIG_PM, we get a harmless build warning: drivers/media/i2c/ov5695.c:1033:12: error: 'ov5695_runtime_suspend' defined but not used [-Werror=unused-function] static int ov5695_runtime_suspend(struct device *dev) ^~~~~~~~~~~~~~~~~~~~~~ drivers/media/i2c/ov5695.c:1024:12: error: 'ov5695_runtime_resume' defined but not used [-Werror=unused-function] static int ov5695_runtime_resume(struct device *dev) This marks the affected functions as __maybe_unused.
