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

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
