Not really.  With CONFIG_SYSCTL=n this change will cause a compile
warning and will bloat up vmlinux.

I'll rewrite the changelog to

: Move watchdog_disable_all_cpus() outside of the ifdef so that it is
: available if CONFIG_SYSCTL is not defined.  This is preparation for
: "watchdog: implement error handling in update_watchdog_all_cpus() and
: callers".
