They're super useful if you want to keep developing a particular driver that has been changed elsewhere, since they ensure the avoidance of merge-conflicts at merge time. If you're not attempting to make further changes, there shouldn't be any requirement to pull them. > I'm not sure if this makes trouble for Greg to pull v2 or MFD tree. Honesty, I'd just leave it as it is. It would have been more problematic if a patch which appears earlier in the set was missing, since this may hurt bisectability or render a tree un-buildable. As it stands, it's the last patch, which no other patch in the series should depend on. -- Lee Jones [李琼斯]
