The NULL initialization of the pointers assigned by kzalloc() or kunit_kzalloc() first is not necessary, because if the kzalloc() or kunit_kzalloc() failed, the pointers will be assigned NULL, otherwise it works as usual. so remove it.

...Vetter <daniel.vetter at ffwll.ch> One thought on testing all this: I think long term some unti tests, where we have a fake driver doing fake mst branch/ports and a bunch of allocations and then checking that it all works and validates would be nice.

This patchset does some cleaning up of the atomic VCPI helpers for MST, and converts nouveau over to using them. I would have included amdgpu in this patch as well, but at the moment moving them over to the atomic helpers is nontrivial.
