5.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Maíra Canal <mcanal@xxxxxxxxxx>
[ Upstream commit e4b5ccd392b92300a2b341705cc4805681094e49 ]
After a job completes, the corresponding pointer in the device must
be set to NULL. Failing to do so triggers a warning when unloading
the driver, as it appears the job is still active. To prevent this,
assign the job pointer to NULL after completing the job, indicating
the job has finished.
Fixes: 14d1d1908696 ("drm/v3d: Remove the bad signaled() implementation.")
