Subject: drm/vc4: gem: Add a managed action to cleanup the job queue
Git-commit: 171a072b4699b4bf79cd1bbbcd05a53d40903034
Patch-mainline: v5.10-rc3
References: jsc#SLE-15318
The job queue needs to be cleaned up using vc4_gem_destroy, but it's
not used consistently (vc4_drv's bind calls it in its error path, but
doesn't in unbind), and we can make that automatic through a managed
action. Let's remove the requirement to call vc4_gem_destroy.
Fixes: d5b1a78a772f ("drm/vc4: Add support for drawing 3D frames.")
