This series introduces DRM reference counting APIs that are consistent with other reference counting APIs in the kernel. They are also much shorter. Compatibility aliases are added to keep existing code working and will stay in place until all users of the old APIs are gone.
All occurrences of the old APIs in the core are already replaced by this series, and a semantic patch is provided that allows drivers to be converted automatically. I plan on generating patches against the drivers once the new functions have been merged and send them out to their respective maintainers.
Oh, and this fixes one of the items in our recently added TODO list.
Thanks, Thierry
