[ Upstream commit 630a1dec3b0eba2a695b9063f1c205d585cbfec9 ]
When dwc3_gadget_soft_disconnect() fails, dwc3_suspend_common() keeps
going with the suspend, resulting in a period where the power domain is
off, but the gadget driver remains connected. Within this time frame,
invoking vbus_event_work() will cause an error as it attempts to access
DWC3 registers for endpoint disabling after the power domain has been
completely shut down.
Abort the suspend sequence when dwc3_gadget_suspend() cannot halt the
controller and proceeds with a soft connect.

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.
