C producer doesn't reproduce the problem on 4.19-rc5. Does this C producer
depend on state of the machine? i.e what is the status of vhci_hcd - are
there any devices attached?

I can see the problem looking at the code and fix is easy. However, I would
like be able to reproduce it and verify the fix works. Also this would be a
good regression for the driver I could consider adding to selftests.
