[PATCH v2 0/7] Replace ttm_bo_{unref, reference} with ttm_bo_{get|put}

[Thomas Zimmermann]

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
