Return USB_GADGET_DELAYED_STATUS from the setup() callback for 0-length transfers as a workaround to stop some UDC drivers (e.g. dwc3) from automatically proceeding with the status stage. This workaround should be removed once all UDC drivers are fixed to always delay the status stage until a response is queued to EP0.

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.
