This submission is modifying two different patch files (one of which I think should not be touched), and reverting something that was already accepted upstream.
I would suggest that you first take latest upstream code, then do any needed modifications there, then submit them upstream and backport to the recipe.
Also the patch file metadata is changed and important information is being removed.

The issue that the patch is aiming to address could also be explained better, particularly the step by step scenario of where the breakage happens would help.
