Because of dwc2_hsotg_ep_stop_xfr() function uses poll mode, first need to mask GINTSTS_GOUTNAKEFF interrupt. In Slave mode GINTSTS_GOUTNAKEFF interrupt will be aserted only after pop OUT NAK status packet from RxFIFO. In dwc2_hsotg_ep_sethalt() function before setting DCTL_SGOUTNAK need to unmask GOUTNAKEFF interrupt. Tested by USBCV CH9 and MSC tests set in Slave, BDMA and DDMA. All tests are passed.

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.
