Sure. I am not the maintainer. They have to make the final decision. imx-drm is still in staging.

One thing I would ask is that the subsequent submissions do not thread onto the previous submission. It may seem a good idea (people claim that it allows the previous reviews to be trivially found) but these people forget an important side effect from this behaviour - when looking at the message index in a threaded mail reader (like mutt), each reply to a thread moves the subject line by three characters to the right. What this means is that after about five or six iterations of the submission, there is no longer any subject line visible. Moreover, it means that with lesser iterations, it becomes much more difficult to see /any/ of the review thread structure. I would suggest that if you do want to connect the subsequent submissions, please use the same reference message for each submission. In other words, rather than: v1 0/2 +- v1 1/2 +- v1 2/2 +- v2 0/2 +- v2 1/2 +- v2 2/2 +- v3 0/2 +- v3 1/2 +- v3 2/2 ... This is done instead: v1 0/2 +- v1 1/2 +- v1 2/2 +- v2 0/2 | +- v2 1/2 | +- v2 2/2 +- v3 0/2 | +- v3 1/2 | +- v3 2/2 ... which is a compromise between threading the messages together, and keeping stopping the thread pushing the subject line completely off the right hand side of the screen. In this case, I'd suggest a reference of: 1415793593-5075-1-git-send-email-andy@rock-chips.com which is the v8 covering message which started this big thread.
