I'm going to need to keep that because I need to know if it's running
in the interrupt handler, and wdd->lock is a mutex.

Shouldn't that come first, before unregistering the timer ?
No, because wdd->dev is used in the interrupt handler. I will have to
move registration of the interrupt to after creating the watchdog
because it could currently be used before wdd->dev is set.
Does unregistering the timer disable the interrupt ?
Thanks,
