So it seems that commit
8bf0cb97edb6 ("drm/amd/display: Move dml2_destroy to non-FPU compilation unit")
is the commit that fixes the issue, but is missing the appropriate tags:
Reported-By: Bert Karwatzki <spasswolf@web.de>
Fixes: 3539437f354b ("drm/amd/display: Move FPU Guards From DML To DC - Part 3")
Please fix this.
