Michael Grzeschik 3df5497b91 usb: dwc3: ep0: Don't reset resource alloc flag (including ep0) 
[ Upstream commit 72fca8371f ]

The DWC3_EP_RESOURCE_ALLOCATED flag ensures that the resource of an
endpoint is only assigned once. Unless the endpoint is reset, don't
clear this flag. Otherwise we may set endpoint resource again, which
prevents the driver from initiate transfer after handling a STALL or
endpoint halt to the control endpoint.

Commit f2e0eee470 ("usb: dwc3: ep0: Don't reset resource alloc flag")
was fixing the initial issue, but did this only for physical ep1. Since
the function dwc3_ep0_stall_and_restart is resetting the flags for both
physical endpoints, this also has to be done for 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.
