Good point!

I totally agree. I opted for passing a pointer to the driver to modify:
void watchdog_set_nowayout(struct watchdog_device *wdd, struct driver
*drv, bool nowayout)
I'd think this would work from a layering perspective.

Not yet. I first wanted to make sure if it makes sense, at all. But will
do for later versions.
Thanks for the review,
