From: Gerd Hoffmann <kraxel@xxxxxxxxxx> [ Upstream commit 8c34cd1a7f089dc03933289c5d4a4d1489549828 ] 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. Don't consider pci_request_region() failure for the framebuffer region as fatal error to workaround this issue.
