Michal Vrastil c17418f43a Revert "usb: gadget: composite: fix OS descriptors w_value logic" 
commit 51cdd69d6a upstream.

This reverts commit ec6ce7075e.

Fix installation of WinUSB driver using OS descriptors. Without the
fix the drivers are not installed correctly and the property
'DeviceInterfaceGUID' is missing on host side.

The original change was based on the assumption that the interface
number is in the high byte of wValue but it is in the low byte,
instead. Unfortunately, the fix is based on MS documentation which is
also wrong.

The actual USB request for OS descriptors (using USB analyzer) looks
like:

Offset  0   1   2   3   4   5   6   7
0x000   C1  A1  02  00  05  00  0A  00

C1: bmRequestType (device to host, vendor, interface)
A1: nas magic number
0002: wValue (2: nas interface)
0005: wIndex (5: get extended property i.e. nas interface GUID)
008E: wLength (142)

The fix was tested on Windows 10 and Windows 11.

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.
