[ Upstream commit 77adb8bdf4227257e26b7ff67272678e66a0b250 ] The DWC3 runtime suspend routine checks for the USB connected parameter to determine if the controller can enter into a low power state. The connected state is only set to false after receiving a disconnect event. However, in the case of a device initiated disconnect (i.e. UDC unbind), the controller is halted and a disconnect event is never generated. Set the connected flag to false if issuing a device initiated disconnect to allow the controller to be suspended.

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.
