However, how about tagging V2, V3.. into patches? For instance, '[PATCH V2 3/7] drm/exynos: Renaming DP training vswing pre emph defines' It will be helpful, in order to prevent the same mistakes happening again. Also, the patch looks good.

Actually I had bumped the version in the cover letter. Because last time I had changed the version of all the patches (for some other feature), somebody asked me to just change the version at the top when it is a series. Also, this was a different patch altogether done using cocci, so thought it should be fine. Will take care next time :) Thanks, Sonika Also, the patch looks good.
