The conflict originated as I applied cffcb42c57686 on drm-misc-fixes. I carefully followed the dim procedure as I know it, so I'm not sure I did anything wrong, but if I did I apologize. The steps I did are: - dim update-branches - dim checkout drm-misc-fixes - dim b4-shazam URL - dim checkpatch+sparse ... - dim push-branch drm-misc-fixes One thing with this procedure is that dim push-branch pushes first, then finds out any conflicts. I wonder whether dim could be changed to find any conflicts before pushing. As soon as dim push-branch warned me about the conflict I tried solving it myself as per [0], but the patches on drm-misc-next (3ea699b56d31c) changed the codebase completely and was unable to sort it out fully. I at least fixed the conflict at a pure patch application level, so I would expect the rerere cache would avoid future conflicts. I was wrong apparently. It had worked in the past, no idea what went wrong this time. Then, as far as the original bug is concerned, I notified the involved patch authors [1] hoping they could find out whether there is the same bug in the drm-misc-next code and fix it if needed. If there is anything I should have done differently I'd be happy to know in order to adjust my process in the future.
