Linux 7.0 Brings An EFI Framebuffer Quirk For Valve's Steam Deck

The EFI subsystem updates have been merged for the in-development Linux 7.0 kernel. Worth mentioning here is a new quirk for helping Valve's Steam Deck handheld.

Tvrtko Ursulin of Igalia landed a fix to the EFI system frame-buffer code for fixing the EFIDRMFB and SimpleDRMFB frame-buffer drivers on Valve's Steam Deck. This quirk/fix is ultimately to allow using the frame-buffer drivers in the correct orientation and ensuring a fake mode isn't used that could lead to corrupted rendering.
