This patch set replaces functions named {un,reference} by their
{put,get} counterparts. Affected data types are struct struct drm_framebuffer,
struct drm_gem_object, and struct drm_device.

With the reference-counting functions being named {put,get}, the DRM
interface is more aligned to Linux kernel nameing standard. The patch
set does not change driver-internal interfaces.

Thomas Zimmermann (3):
  drm/msm: Replace drm_framebuffer_{un/reference} with put,get functions
  drm/msm: Replace drm_gem_object_{un/reference} with put,get functions
  drm/msm: Replace drm_dev_unref with drm_dev_put

This patch unifies the naming of DRM functions for reference counting
of struct drm_device. The resulting code is more aligned with the rest
of the Linux kernel interfaces.
