I'm the one who added the runtime warning and I agree that a build
time warning would have been more suitable. Exacly how to implement
that in this specific case is another question. I'm open to
suggestions. =)

The purpose was simply to move over to the new interface sooner than later.

It should be pretty trivial. The tricky part is what gets used when in
the cases of CONFIG_HIBERNATION and CONFIG_SUSPEND. The dev_pm_ops
comment in include/linux/pm.h should guide people in the right
direction.

Thanks for your help!
