I suppose that's fine, although I wonder if it'll cause churn should we
ever need to add code to the tail end of the function.

BTW, why were all the similar patches that had nothing to do with Tegra
sent to the linux-tegra@ mailing list? You also didn't CC the
maintainers of drivers/gpu/drm/tegra/ on this patch. Plus this patch has
nothing to do with the rtc-linux@ mailing list.
