Without .shutdown(), watchdog might reset the system during power off.
For example, if watchdog's timeout is set to 30s, then it is reset to
zero by mtk_wdt_ping(). During power off, no app will ping watchdog,
but watchdog is still running and may trigger reset.

is the plan to land these two patches via Guenter's watchdog tree [0]?
[0] git://

That is Wim's tree, and Wim is the maintainer ;-).

I have the patches queued in my tree [1], and I plan to send a pull request
to Wim this week or early next week.
