I foresee that there will be difficulties maintaining it my side in the long run.

I asked you at v2 to go through all comments and respond to each of them or implement each of them. BTW, I asked for subject to keep only one, first "media" prefix: "Subject: just one media (first). " but you kept the second "media". Best regards, Krzysztof

Go back to your first posting. I asked to remove one media and keep only one - the first. I did not ask to re-shuffle the prefixes. Best regards, Krzysztof

Go back to your first posting. I asked to > remove one media and keep only one - the first. I did not ask to > re-shuffle the prefixes. Yes, let me sum it up v1 title is w.r.t https://patchwork.kernel.org/project/linux-arm-msm/patch/20240222-b4-camss-sc8280xp-v6-1-0e0e6a2f8962@linaro.org/ then extra "camss" pre-fix keyword and "binding" post-fix is not needed. v2 wrongly remove all prefixes and correctly removed post-fix v3 added correct prefix, removed redundancy "camss" prefixes but changelog still refer to old sc8280xp style The title now should be fine. So I will modify the changelog only. So there are 2 todo items as above. Other than above, all review items are addressed. Plz confirm.

Where did I write anything about camss? I already said it twice that I meant "media". Best regards, Krzysztof

Appreciated if some developer is willing to take over it too.
