Arnoud Willemsen da1880c7b6 HID: Elecom: Add support for ELECOM M-XT3DRBK (018C) 
[ Upstream commit 12adb96965 ]

Wireless/new version of the Elecom trackball mouse M-XT3DRBK has a
product id that differs from the existing M-XT3DRBK.
The report descriptor format also seems to have changed and matches
other (newer?) models instead (except for six buttons instead of eight).
This patch follows the same format as the patch for the M-XT3URBK (018F)
by Naoki Ueki (Nov 3rd 2025) to enable the sixth mouse button.

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 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.
