With CONFIG_PM, we get a harmless build warning: drivers/i2c/busses/i2c-i801.c:1723:12: warning: ‘i801_resume’ defined but not used [-Wunused-function] static int i801_resume(struct device *dev) ^~~~~~~~~~~ drivers/i2c/busses/i2c-i801.c:1714:12: warning: ‘i801_suspend’ defined but not used [-Wunused-function] static int i801_suspend(struct device *dev) ^~~~~~~~~~~~ This marks the affected functions as __maybe_unused.
