in my opinion this should be:

		...
		if (!node)
			return IOMEM_ERR_PTR(-ENODEV);

		dev_warn(dev, "Finding PMU node via deprecated method, update your DTB\n");

Because if you don't have both "samsung,pmu-syscon and "pmu" then
the warning should not be printed and you need to return -ENODEV.

... and... "*please* update your DTB", the user might get upset
and out of sheer spite, decides not to do it – just because! :)
