[PATCH 6.6 107/121] drm/virtio: Fix type of dma-fence context variable

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.6-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")
