[ Upstream commit4e8ef34e36] When work in gadget mode, currently driver doesn't update software level link_state correctly as link state change event is not enabled for most devices, in function dwc3_gadget_suspend_interrupt(), it will only pass suspend event to UDC core when software level link state changes, so when interrupt generated in sequences of suspend -> reset -> conndone -> suspend, link state is not updated during reset and conndone, so second suspend interrupt event will not pass to UDC core. Remove link_state compare in dwc3_gadget_suspend_interrupt() and add a suspended flag to replace the compare 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.
