In the Linux kernel, the following vulnerability has been resolved:
media: ti: vpe: unwind v4l2 device registration on probe error
If the vpe_top resource is missing, vpe_probe() returns -ENODEV after v4l2_device_register() has succeeded. Probe failures do not call the drivers remove callback, so the v4l2 device remains registered on that error path.
Route that failure through the existing v4l2_device_unregister() unwind label, matching the other errors after v4l2_device_register().
