Subject[PATCH v4 3/7] arm: Support restart through restart notifier call chain
Date
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>
---
v4: No change.
v3: Use wrapper function to execute notifier call chain.
v2: Only call notifier call chain if arm_pm_restart is not set.
Do not include linux/watchdog.h.
