could you _please_ remove this coment? This kind of comment (if at all)
should be part of the commit message (which is the case more or less).
IIRC, Grygorii specifically wanted to keep this comment in dra7xx, but
True.
I do agree that this level of detail is more appropriate for a changelog.
If Grygorii and Kishon don't object, I can update the patch to remove it.
But no objections from my side. Thanks a lot.
