6.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dmitry Osipenko <dmitry.osipenko@xxxxxxxxxxxxx>
commit 445d336cd15860f1efb441e6d694f829fbf679eb upstream.
Type of DMA fence context is u64. Fence-waiting code uses u32 for the
context variable, fix it.
Fixes: e4812ab8e6b1 ("drm/virtio: Refactor and optimize job submission code path")
