Good to hear the upstream fix resolves it. Separate question though, are
you still planning to carry the IPQ4019 migration to the new flattened
dwc3-qcom glue (patch 3/3 + the DT compatible change)? It may be worth
keeping regardless of the quirk, since it fixes the legacy glue's race
conditions and gives you a way to pass custom dwc3 properties from the
glue to the core if you need to in the future.

Thanks,
