[RFC: 2.6 patch] drivers/char/drm/: possible cleanups

[Adrian Bunk]

This patch contains the following possible cleanups:
- make the following needlessly global function static:
  - drm_bufs.c: drm_addbufs_fb()
- remove the following unused EXPORT_SYMBOL's:
  - drm_agpsupport.c: drm_agp_bind_memory
  - drm_bufs.c: drm_rmmap_locked
  - drm_bufs.c: drm_rmmap
  - drm_stub.c: drm_get_dev
