My preference would be easy to use helpers for drivers because this is easy to get wrong. I think we need to discuss with the creators of that API: a) if the drm/exynos driver does the right thing(tm) b) if these functions should be generic helpers c) when to clear the pointer (a bit related to a)) Niklas, do you have an interest to do that? Or would you rather go with SDHI hacking? :) I can do it, too.
