This file was split in commit 5d945cbcd4b16a29d6470a80dfb19738f9a4319f ("drm/amd/display: Create a file dedicated to planes") and 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 reported 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.
