Thanks, I made it in a different way by simply adding helpers to the
pm_opp.h which use devm_add_action_or_reset(). This doesn't require to
add new kernel symbols.

I will prefer to add it in core.c itself, and yes
devm_add_action_or_reset() looks better. But I am still not sure for
which helpers do we need the devm_*() variants, as this is only useful
for non-CPU devices. But if we have users that we can add right now,
why not.

static inline int devm_pm_opp_of_add_table(struct device *dev)
{
	int err;

	err = dev_pm_opp_of_add_table(dev);
	if (err)
		return err;

	err = devm_add_action_or_reset(dev, (void*)dev_pm_opp_remove_table,
				       dev);
	if (err)
		return err;

	return 0;
}
