Re: drivers/watchdog/geodewdt.c: build fix

[David Brigada]

I was trying to compile a kernel with this support, and noticed this 
bug, too.  The interface was changed in commit 
fa28e067c3b8af96c79c060e163b1387c172ae75, with the message:

I may be reading this incorrectly, but it seems that to do this 
correctly, we would either need to drop module support for this driver 
or rework the MFGPT code.  I'm not sure there's a kernel hook for 
dropping ponies from the sky quite yet.

Thanks,
David Brigada
