Replace {un/reference} with {put,get} functions

This patch set replaces functions named {un,reference} by their {put,get} counterparts. Each patch also removes the replaced functions from the DRM core and deletes them from the related Coccinelle script. Affected data types are struct drm_connector, struct drm_framebuffer, struct drm_gem_object, and struct drm_device.

This change fixes the related item on the DRM TODO list.

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.

Possible future changes: Most of DRM's remaining {un/ref} functions perform additional tasks besides reference counting and should probably not be renamed. Exceptions are ttm_bo_{reference,unref} and ttm_object_file_{un/ref}. These functions mostly perform reference counting, but would require additional changes to the calling code besides renaming.

Thomas Zimmermann (7):
drm: Replace drm_connector_{un/reference} with drm_connector_{put,get}
drm: Replace drm_framebuffer_{un/reference} with

    drm_framebuffer_{put,get}
  drm: Replace drm_gem_object_{un/reference} with
    drm_gem_object_{put,get}

drm: Replace __drm_gem_object_unreference with __drm_gem_object_put
drm: Replace drm_gem_object_unreference_unlocked with put function
drm: Replace drm_dev_unref with drm_dev_put
drm: Clean up after DRM put/get conversion
