Dropping was the right call - I have since removed it from 
drm-intel-fixes as well.

Root cause was a bad Fixes: tag in that patch which caused it to be 
wrongly cherry-picked and I did not build test before pushing.

We can't edit the wrong Fixes: tag now, so for future reference only, 
2e872d87cbf2 ("drm/i915: delete shadow "ret" variable") should not be 
backported to 5.17 by anyone.

Wrong tag:
Fixes: f6c466b84cfa ("drm/i915: Add support for moving fence waiting")

Correct tag should have been:
Fixes: 2f6b90da9192 ("drm/i915: Use vma resources for async unbinding")
