This patch fixes the error "ravb 11c20000.ethernet eth0: failed to switch
device to config mode" during unbind.
We are doing register access after pm_runtime_put_sync().
We usually do cleanup in reverse order of init. Currently in
remove(), the "pm_runtime_put_sync" is not in reverse order.
Probe
reset_control_deassert(rstc);
pm_runtime_enable(&pdev->dev);
pm_runtime_get_sync(&pdev->dev);
remove
pm_runtime_put_sync(&pdev->dev);
unregister_netdev(ndev);
..
ravb_mdio_release(priv);
pm_runtime_disable(&pdev->dev);
Consider the call to unregister_netdev()
unregister_netdev->unregister_netdevice_queue->rollback_registered_many
that calls the below functions which access the registers after
pm_runtime_put_sync()
1) ravb_get_stats
2) ravb_close
