I just bisected this bug. "First bad commit" is d391c58271072d0b0fad93c82018d495b2633448 Author: Javier Martinez Canillas Date: Fri Jun 25 15:09:46 2021 +0200 drivers/firmware: move x86 Generic System Framebuffers support The x86 architecture has generic support to register a system framebuff= er platform device. It either registers a "simple-framebuffer" if the conf= ig option CONFIG_X86_SYSFB is enabled, or a legacy VGA/VBE/EFI FB device. But the code is generic enough to be reused by other architectures and = can be moved out of the arch/x86 directory. This will allow to also support the simple{fb,drm} drivers on non-x86 E= FI platforms, such as aarch64 where these drivers are only supported with = DT.
