Should be fixed by https://patchwork.freedesktop.org/patch/230831/ which is merged into amd-staging-drm-next

Just tested with 4.18-rc6 that has this patch applied. Still getting the use-after-free. Looking at this patch, this seems to fix another bug:

BUG: KASAN: use-after-free in amdgpu_dm_atomic_commit_tail.cold.50+0x13d/0x15a [amdgpu]

whereas this one is:

BUG: KASAN: use-after-free in drm_atomic_helper_wait_for_flip_done+0x212/0x270

I'll try the patch from Daniel Vetter now.
