While the END_TRANSFER command is sent but not completed, any request dequeue during this time will cause the driver to issue the END_TRANSFER command. The driver needs to submit the command only once to stop the controller from processing further. The controller may take more time to process the same command multiple times unnecessarily. Let's add a flag DWC3_EP_END_TRANSFER_PENDING to check for this condition.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
