NAME
       drm_framebuffer_cleanup - remove a framebuffer object

SYNOPSIS
       void drm_framebuffer_cleanup(struct drm_framebuffer * fb);

ARGUMENTS
       fb
	   framebuffer to remove

DESCRIPTION
       Cleanup references to a user-created framebuffer. This function is
       intended to be used from the drivers ->destroy callback.

       Note that this function does not remove the fb from active usuage - if
       it is still used anywhere, hilarity can ensue since userspace could
       call getfb on the id and get back -EINVAL. Obviously no concern at
       driver unload time.

       Also, the framebuffer will not be removed from the lookup idr - for
       user-created framebuffers this will happen in in the rmfb ioctl. For
       driver-private objects (e.g. for fbdev) drivers need to explicitly call
       drm_framebuffer_unregister_private.
