tja1102_p0_probe() schedules work to register the second port. That work uses the Port 0 private data and phydev. The private data is devm-allocated, but the driver does not wait for the pending work on remove. Store the Port 0 private data in phydev->priv and add a remove callback. The callback cancels the registration work before devres teardown frees the state. This issue was found by a static analysis tool.
