Yes, the reason is there's a patch conflict and I still have to find out how to handle it. Patch 3 by the rules [0] should go to drm-misc-fixes because the bug (added by [1]) is already on Linus' master tree (since v6.17), but it does not apply there due to a conflict with an unrelated change [2] currently on drm-misc-next. Note that [1] and [2] are the two commits mentioned in your 'Fixes: 'tags. I had a chat with Maxime on #dir-devel about how to handle this situation but still haven't got a final answer. I guess the correct way is: 1. apply patch 3 on drm-misc-next, where it applies cleanly 2. send a modified patch for drm-misc-fixes, to fix ASAP the master branch Would you send the patch as in item 2, so it can be applied to drm-misc-fixes and have master fixed ASAP? Note iit should not mention [2] in the Fixes: tag because [2] is not yet on master. I can send it of course but you can test on hardware so that would be the best option (and I'm a bit overloaded at the moment).
