Duplicates like this happen all the time due to their bizarre workflow that causes this to happen at least once a release, and is still a major pain to deal with. I dread the -rc1 merge window each time for the drm patches and put them off until I have gotten through everything else. Can you please work with those developers to make this go better to prevent this from constantly happening? thanks, greg k-h
