Subject[PATCH] i2c: i801: mark PM functions as __maybe_unused
Date
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.

Fixes: a9c8088c7988 ("i2c: i801: Don't restore config registers on runtime PM")
