So please use it as an example. > > I don't want to take any credit out of it. I just re-base on the new kernel. > I could not test this patch as it meant for exynos5440 boards. Are you sure? I think the driver is used on almost all of Exynos SoCs (Exynos4, Exynos5250, Exynos542x). Untested code should not go to the kernel. Additionally you should mark it as not-tested. Marking such patch as non-tested could help you finding some independent tests (tests performed by someone else). To summarize my point of view: 1. Unless Vivek's says otherwise, please give him the credits with proper "from" field. 2. Issues mentioned in previous mail should be addressed (missing IS_ERR(), how disabling the regulator during suspend affects waking up). 3. The patchset must be tested, even after rebasing.
