You're pretending to portray the situation as if I have been notoriously causing merge conflicts in linux-next which did not take place. Just to recap what this discussion is about: On 7 Apr 2019: 1. I sent pull request [0]. 2. 45 minutes later I updated it after discovering one omission [1]. It was rather small chance for it to be pulled as quickly as that. And even if it happened it wouldn't have been much harmful - we wouldn't have lost e.g. weeks of testing in linux-next due to that fact. On 21 May 2019: 3. I sent another pull request [2] to you and REGULATOR maintainers. After it turned out that lack of feedback from REGULATOR maintainers was caused by failing to send them the exact copies of patches to review, I informed you about possible need for updating the branch. Afterwards I received a reply from you saying that you hadn't pulled the branch anyway. At that point I was sure that neither MFD nor REGULATOR tree contains the patches. And only after that I updated the branch. > Until you can provide me with an assurance that you will not keep > updating/changing the supposedly immutable pull-requests you send out, > I won't be pulling any more in. I can just uphold the assurance which is implicitly assumed for anyone who has never broken acclaimed rules. As justified above.

Won't the change be a dependency for [PATCH v4 1/6] ? In each case, having all the commits in one set (and branch) should simplify the integration. -- Best regards, Jacek Anaszewski
