From: Jonathan Cameron <Jonathan.Cameron@xxxxxxxxxx> Letting the compiler remove these functions when the kernel is built without CONFIG_PM support is simpler and less error prone than the use of #ifdef based config guards. Removing instances of this approach from IIO also stops them being copied into new drivers.
