I wanted to give that patch set a shot but could not figure out against what to get it cleanly applied. Could you reveal its baseline or better yet a git branch ready for testing? > Simon Glass (23): > ? tegra: keyboard: Fix the init order > ? dm: video: Flush the cache after a puts() > ? tegra: mmc: Fix comments in the MMC driver init > ?
