[Bug][5.18-rc0] Between commits ed4643521e6a and 34af78c4e616, appears warning "WARNING: CPU: 31 PID: 51848 at drivers/dma-buf/dma-fence-array.c:191 dma_fence_array_create+0x101/0x120" and some games stopped working.

Hi Mikhail,
those are two independent and already known problems.
The warning triggered from the sync_file is already fixed in
drm-misc-next-fixes, but so far I couldn't figure out why the games
suddenly doesn't work any more.
There is a bug report for that, but bisecting the changes didn't yielded
anything valuable so far.
So if you can come up with something that would be rather valuable.
Regards,
Christian.
