These fine-grained dependencies tend to be useful on very low-end systems where every byte of memory counts, but on modern platforms such as Exynos the maintainability of the code trumps the last few bytes of savings, I'd say. -Olof -- To unsubscribe from this list: send the line unsubscribe linux-samsung-soc in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
