commit c38fa07dc69f0b9e6f43ecab96dc7861a70c827c upstream. Currently we don't configure correctly the wake events after unplug of device router. What can happen is that the downstream ports of host router will be configured to wake on: USB4-wake and wake-on-disconnect, but not on wake-on-connect. This may cause the later plugged device not to wake the domain and fail in enumeration. Fix this by clearing downstream port's "USB4 Port is Configured" bit, after unplug of a device router.

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.
