Shutdown of firmware framebuffer has a bunch of problems.  Because
of this the framebuffer region might still be reserved even after
drm_fb_helper_remove_conflicting_pci_framebuffers() returned.

Is that still the fbdev lifetime fun where the cleanup might be delayed if
the char device node is still open?

Yes.
