I keep wondering why your series does not show up in the watchdog patchwork.
Turns out that is not surprising, since you don't copy the watchdog mailing
list. That all but guarantees that it gets lost from my workflow. That is
kind of interesting - there are lots of lists in Cc:, but the two lists
that matter because maintainers need to review it (watchdog and devicetree)
are missing.

Anyway, comment and question below.

Is that (still) correct ? After all, behavior is different for those two now.
Just wondering.
