 I think the first patch which you have taken (which adds new defines) is
 the one from the previous series for the same change. In the second
 version, I have named them as DP_TRAIN_PRE_EMPH_LEVEL_* which was done
 using cocci. Following is from that patch:

Oh, I see. Sorry for annoying you.
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.
