Benjamin Tissoires 9bc089307e HID: bpf: Fix NKRO on Mistel MD770
Mistel MD770 keyboard (using Holtek Semiconductor, Inc. controller) has
a quirk in report descriptor in one of its interfaces (more detail in
the source file). Fix up the descriptor to allow NKRO to work again.

Tested by loading the BPF program and confirming that 8 simultaneous
keypresses work.

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 reStructuredText 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.
