I guess so. In this particular case it was my fault because I pushed to
drm-misc-next with the expectation that there would be a last PR before
the drm-next tree was sent to Torvalds but I missed for a few hours...

So then I had the option for the fixes to miss 6.7 and wait to land in
6.8, or cherry-pick them to the drm-misc-next-fixes branch and pollute
the git history log :(
