("drm/amd/display: Create a file dedicated to planes") the logic in
dm_plane_format_mod_supported() function got changed by a switch logic.
That change broke drm_plane modifiers setting on series 5000 APUs
(tested on OXP mini AMD 5800U and HP Dev One 5850U PRO)
leading to Gamescope not working as reproted on GitHub[1]To reproduce the issue, enter a TTY and run: $ gamescope -- vkcube With said commit applied it will abort. This one restores the old logic, fixing the issue that affects Gamescope.
