This looks completely wrong. If register_framebuffer() fails, then the
work that register_framebuffer() does internally should be cleaned up
and unregister_framebuffer() should not be necessary.

The code looks correct as-is to me, so there's no need to patch it.
If there is a memory leak, that'll be in register_framebuffer() itself.
