Well, I split documentation change and PCI_CONF1_EXT_ADDRESS usage into two patches as those are two different / separate things. Documentation change is a fix (because documentation is wrong) and PCI_CONF1_EXT_ADDRESS is an improvement - code cleanup. And in case if there is a issue with "cleanup" patch it can be reverted without need to revert also "fix" part. This is just information how I looked at these changes and why I decided to split them. > On > the other hand there's really no use in keeping this comment around > after that other patch because the documentation for the new macro lays > out the details already. > > Thierry Ok, whether documentation is needed or not - it is your maintainer decision. Maybe really obvious things do not have to be documented. Also another look at this problem can be that if somebody wrote wrong documentation for it, maybe it is not too obvious? I do not have opinion on this, so choose what is better :-) In any case, wrong documentation (which is the current state) should be fixed (and removal in most case is also proper fix).
