commit 3a49012224ca9016658a831a327ff6a7fe5bb4f9 upstream.
The driver did not unregister the allocated framebuffer, which caused
memory leaks (and memory manager WARNs) when unloading. Also, the
framebuffer device under /dev still existed after unloading.
Add a call to drm_fbdev_cma_fini when unloading the module to prevent
both issues.
