Name
drm_framebuffer_unregister_private — 
     unregister a private fb from the lookup idr
 
Synopsis
| void drm_framebuffer_unregister_private ( | struct drm_framebuffer * fb ); | 
 
Description
   Drivers need to call this when cleaning up driver-private framebuffers, e.g.
   those used for fbdev. Note that the caller must hold a reference of it's own,
   i.e. the object may not be destroyed through this call (since it'll lead to a
   locking inversion).
