The whole drm tree is messed up when it comes to stable patches.
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,
