Thanks, maybe, to avoid similar issues in the future, we should start
removing the ifdef CONFIG_PM_SLEEP and instead annotate such functions
with __maybe_unused. I wonder if we could magically make that happen
with a coccinelle script that looks for SIMPLE_DEV_PM_OPS to know which
functions to annotate... humm.
