commitc8540870afupstream. Prevent -ETIMEDOUT error on .suspend(). e.g. If gadget driver is loaded and we are connected to a USB host, all transfers must be stopped before stopping the controller else we will not get a clean stop i.e. dwc3_gadget_run_stop() will take several seconds to complete and will return -ETIMEDOUT. Handle error cases properly in dwc3_gadget_suspend(). Simplify dwc3_gadget_resume() by using the introduced helper function.

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.
