Thanks for your patch, which is now commit 77849a552d142ef5 ("hwmon:

This makes the driver unselectable if WATCHDOG is not set.

Is there a use case for using this driver without watchdog functionality?
If yes, it might make sense to make the watchdog support optional,
protected by #ifdef CONFIG_WATCHDOG, and change the above to

depends on I2C
select WATCHDOG_CORE if WATCHDOG

If no, please ignore my email.
