Jann Horn 2330b2ba64 usb: raw-gadget: fix handling of dual-direction-capable endpoints
commit 292d2c82b1 upstream.

Under dummy_hcd, every available endpoint is *either* IN or OUT capable.
But with some real hardware, there are endpoints that support both IN and
OUT. In particular, the PLX 2380 has four available endpoints that each
support both IN and OUT.

raw-gadget currently gets confused and thinks that any endpoint that is
usable as an IN endpoint can never be used as an OUT endpoint.

Fix it by looking at the direction in the configured endpoint descriptor
instead of looking at the hardware capabilities.

With this change, I can use the PLX 2380 with raw-gadget.

README

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.
