Conflicts with "watchdog: constify watchdog_ops structures" in my tree.
I rebased my tree to v4.10 (which I should not really have done ;-), but
it still doesn't apply due to "fatal: sha1 information is lacking or useless"
and "error: could not build fake ancestor". The subsequent patches also don't
apply. You may have to wait until after -rc1, rebase your patches, and
resubmit.
