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.
