Probing at device_initcall time lead to perverse cases where the

Load the watchdog driver early to ensure that the kernel is patting it
well before initialising peripherals.

I agree that we need to make sure the watchdog driver is loaded
earlier. I think this is the correct method, but I'll defer to Guenter
on this one.

Just following up on Joel's comments: Is there anything else I need to
address?


No. Sorry, I have been terribly busy. Digging through patch backlog today.
