Merge branch 'dsa-cleanup'

Vladimir Oltean says:

====================
More aggressive DSA cleanup

This series deletes some code which is apparently not needed.

I've had these patches in my tree for a while, and testing on my boards
didn't reveal any issues.

Compared to the RFC v1 series, the only change is the addition of patch 3.
