If the heartbeat module param is not specified we would get an error message watchdog: f1020300.watchdog: driver supplied timeout (4294967295) out of range watchdog: f1020300.watchdog: falling back to default timeout (171) This is because we were initialising heartbeat to -1. By removing the initialisation (thus letting the C run time initialise it to 0) we silence the warning message and the default timeout is still used.
