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.

Out of curiosity: what's going wrong here?

Best regards Thomas

Don't consider pci_request_region() failure for the framebuffer region as fatal error to workaround this issue.
