This entry asked to rename all drm core "*_reference/_unrefence"
functions to "*_get/_put".

Now that this task is complete, we can remove this entry from the TODO
list.

-Switch from reference/unreference to get/put
---------------------------------------------
-
-For some reason DRM core uses ``reference``/``unreference`` suffixes for
-refcounting functions, but kernel uses ``get``/``put`` (e.g.
-``kref_get``/``put()``). It would be good to switch over for consistency, and
-it's shorter. Needs to be done in 3 steps for each pair of functions:
-
-* Create new ``get``/``put`` functions, define the old names as compatibility
-  wrappers
-* Switch over each file/driver using a cocci-generated spatch.
-* Once all users of the old names are gone, remove them.
-
-This way drivers/patches in the progress of getting merged won't break.
