When CONFIG_PM_SLEEP is disabled, we get a couple of harmless warnings:

drivers/net/ethernet/renesas/ravb_main.c:2104:12: error: 'ravb_suspend' defined but not used [-Werror=unused-function]
The simplest solution here is to replace the #ifdef with __maybe_unused
annotations, which lets the compiler do the right thing by itself.

That was the patch I didn't review, sorry about that...

I guess it's safe to have this pointing to the 'struct dev_pm_ops' filled
with NULLs? Looking at the PM code left me somewhat unsure...
