As I already pointed out this is stray change. Why you ignored my comment?

Same Q as per dwapb driver. The CONFIG_PM=n doesn't need these.

This is not a device PM ops actually. Is there any guarantees on the
relationship with CONFIG_PM and these callbacks? If so, I think we
need to have special macros somewhere in include/linux/syscore_ops.h.

Otherwise I'm not sure this will be a good patch at all.
