AMD drm patch workflow is broken for stable trees

Hi all,

As some of you have noticed, there's a TON of failure messages being sent out for AMD gpu driver commits that are tagged for stable backports. In short, you all are doing something really wrong with how you are tagging these.

Please fix it up to NOT have duplicates in multiple branches that end up in Linus's tree at different times. Or if you MUST do that, then give us a chance to figure out that it IS a duplicate. As-is, it's not working at all, and I think I need to just drop all patches for this driver that are tagged for stable going forward and rely on you all to provide a proper set of backported fixes when you say they are needed.

Again, what you are doing today is NOT ok and is broken. Please fix.
