From: Arnd Bergmann <arnd@xxxxxxxx>
Subject: kernel/watchdog: hide unused function
watchdog_update_cpus() is defined unconditionally, but only used when
CONFIG_SYSCTL is defined:
kernel/watchdog.c:608:12: error: 'watchdog_update_cpus' defined but not used [-Werror=unused-function]
This adds another #ifdef around it.
Fixes: mmotm ("kernel/watchdog: provide watchdog_nmi_reconfigure() for arch watchdogs")
