Sorry I had not realized that this patch got queued in the watchdog tree
and relied on the other patches. I ended up not sending the series after
a runtime regression in another driver, combined with the series not
having spent much time in linux-next before the merge window.

I've sent a fixup patch now that will make it do the right thing
regardless of my series, please apply that for v5.4.
