But sysfb_apply_efi_quirks() modifies the global screen_info struct which [sysfb_]parse_mode() parses, so doing it later is too late. This has broken all DMI based quirks for correcting wrong firmware efifb settings when simpledrm is used. To fix this move the sysfb_apply_efi_quirks() call back to its old place and split the new setup of the efifb_fwnode (which requires the platform_device) into its own function and call that at the place of the moved sysfb_apply_efi_quirks(pd) calls.
