Yes, I agree, and admire your insistence on the thing you think right or better. Learn from you. When you suggested this in my v2 post, I made a draft patch at below link according to your suggestion to request people to review. What worried me is that I am not sure it's ignored or disliked after one week of waiting. https://lore.kernel.org/all/YwtND%2FL8xD+ViN3r@MiWiFi-R3L-srv/#related Up to now, seems people don't oppose this generic_ioremap_prot() way, we can take it. So what's your plan? You want me to continue with your patches wrapped in, or I can leave it to you if you want to take over?
