Current sequence utilizes dwc3_gadget_disable_irq() alongside
synchronize_irq() to ensure that no further DWC3 events are generated.
However, the dwc3_gadget_disable_irq() API only disables device
specific events. Endpoint events can still be generated. Briefly
disable the interrupt line, so that the cleanup code can run to
prevent device and endpoint events. (i.e. __dwc3_gadget_stop() and
dwc3_stop_active_transfers() respectively)
Without doing so, it can lead to both the interrupt handler and the
pullup disable routine both writing to the GEVNTCOUNT register, which
will cause an incorrect count being read from future interrupts.

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.
