This patchset cleans up the last remaining callers of ttm_bo_reference and ttm_bo_unref. Calls are replaced with ttm_bo_get and ttm_bo_put, which follow Linux' get/put semantics more closely.
The most notable difference is that ttm_bo_get does not clear the supplied pointer's value. This behaviour is now located in the calling code for cases where it might be required.
v2: * rebased onto drm-tip
