OK, I will split the patch in the next version. > > > Print warning if the sleep script is loaded before wakeup script. > > Because there is a chance that the Power chip may go to sleep before > > the wakeup script is completely loaded, which can cause a system hang. > > OK, but your patch doesn't add this warning. It's already there. The variable order is updated to '1' during wakeup script for P1_P2 is populated, and the warning is printed while loading sleep script if order is set to '1'(ie: warning is printed, if wakeup script is loaded before loading the sleep script). But actually we should print the warning, only if wakeup script is not loaded before loading the sleep script.
