Implementing a restart handler in a module don't make sense

Why not? I was just going to do that, but I got greeted by:
Because you should register a restart handler instead, like the other
drivers in the same directory now do.
ERROR: "arm_pm_restart" [drivers/power/reset/rmobile-reset.ko] undefined!
So now we have to make sure all reset drivers for a zillion different
hardware devices are builtin, and can't be modular?
No. All those drivers need to do is to register a restart handler using
the API provided in the patch series.
Ultimately all restart handlers should do that and arm_pm_restart should
go away entirely. That was the point of the patch series.
