commit c894ac44786cfed383a6c6b20c1bfb12eb96018a Author: Thomas Zimmermann <[email protected]> Date: Tue Jan 25 10:12:18 2022 +0100 fbdev: Hot-unplug firmware fb devices on forced removal commit 27599aacbaefcbf2af7b06b0029459bbf682000d upstream. Hot-unplug all firmware-framebuffer devices as part of removing them via remove_conflicting_framebuffers() et al. Releases all memory regions to be acquired by native drivers. Firmware, such as EFI, install a framebuffer while posting the computer. After removing the firmware-framebuffer device from fbdev, a native driver takes over the hardware and the firmware framebuffer becomes invalid. Firmware-framebuffer drivers, specifically simplefb, don't release their device from Linux' device hierarchy. It still owns the firmware framebuffer and blocks the native drivers from loading. This has been observed in the vmwgfx driver. [1] Initiating a device removal (i.e., hot unplug) as part of remove_conflicting_framebuffers() removes the underlying device and returns the memory range to the system.

Reverting it fixes the problem, and won't cause issues for other platforms, so we revert it.
