Looks like this one falls through the cracks, it didn't reach mainline
and therefore wasn't applied to stable branches.

I just checked, it still apply properly on today's linux-next branch.

Possibly that happened because you did not copy the watchdog mailing list.

... and your other patches were not sent to the watchdog mailing list either,
so you should not expect them to be picked up either.

Whoops, thanks for the heads up, I wonder how I managed to mess up that
at that time, I usually take care of that. The other series need
respinning anyway so I can fix it for v2 (if any).
