I realized a couple of weeks ago that I never sent it to Wim who is listed as the maintainer of watchdog device drivers or the linux-watchdog maillist so I did so at that time and haven't heard anything yet. The original patch was: http://lists.infradead.org/pipermail/linux-arm-kernel/2015-May/347168.html The 2nd version was: http://lists.infradead.org/pipermail/linux-arm-kernel/2015-June/348761.html It's likely that a rebase/resubmit (including the proper list) may result in a better outcome.
