This file was split in commit 5d945cbcd4b16a29d6470a80dfb19738f9a4319f
("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.

Hi,
First of all, thanks a lot for this patch.
You can drop asic_id since it is not used anymore.
Thanks

> ("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.
