| |
The kernel core now supports a notifier call chain for system restart functions.
With this change, the arm_pm_restart callback is now optional, so check if it is set before calling it. Only call the notifier functions if arm_pm_restart is not set.
Signed-off-by: Guenter Roeck <linux@roeck-us.net> --- v2: Only call notifier call chain if arm_pm_restart is not set Do not include linux/watchdog.h
