This patch replace instances of drm_gem_object_reference/unreference with
*_get/put() suffixes, because get/put is shorter and consistent with the
kernel use of *_get/put() suffixes.
This was done with the following Coccinelle script:
@r1@
expression e;
@@
(
-drm_gem_object_reference(e);
+drm_gem_object_get(e);
|
-drm_gem_object_unreference(e);
+drm_gem_object_put(e);
|
-drm_gem_object_unreference_unlocked(e);
+drm_gem_object_put_unlocked(e);
)
