6   Cleanup framebuffer. This function is intended to be used from the drivers
7   -&gt;destroy callback. It can also be used to clean up driver private
8   framebuffers embedded into a larger structure.
9   </p><p>

11   Note that this function does not remove the fb from active usuage - if it is
12   still used anywhere, hilarity can ensue since userspace could call getfb on
13   the id and get back -EINVAL. Obviously no concern at driver unload time.
14   </p><p>
15
16   Also, the framebuffer will not be removed from the lookup idr - for
17   user-created framebuffers this will happen in in the rmfb ioctl. For
18   driver-private objects (e.g. for fbdev) drivers need to explicitly call
19   drm_framebuffer_unregister_private.
