No, not really. patch 23-26 adds comments to panel drivers where the existing implementation contradicts the information in the panel's documentation. I was not able to locate any document for the Sony acx565akm panel. I opted to not change the behavior of the panel drivers regarding to this since I don't have access to neither of the boards with the given displays and this was the configuration they were using and I assume they were/are working fine. >> The rest of the patches are most mechanical ones.
