v2:

Do you want to stick to power[-_ ]off consistently throughout?

I guess you'll want to fix all of these before I review the MFD
patches?

- Add defines for default priorities
- Use raw notifiers protected by spinlocks instead of atomic notifiers
- Add register_poweroff_handler_simple
- Add devm_register_power_off_handler

power-off

power_off, no?

That is describing text, so hopefully I can use real words here and
don't have to use a term derived from variable and function names.

Sure, I can change poweroff in all describing text to power-off
if that is preferred, no big deal.

Thanks,
Guenter
