[PATCH 5.15 04/22] HID: multitouch: Add support for B2402FVA track point

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

5.15-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Stefan Blum <stefanblum2004@gmail.com>

[ Upstream commit 1a5cbb526ec4b885177d06a8bc04f38da7dbb1d9 ]

By default the track point does not work on the Asus Expertbook B2402FVA.

>From libinput record i got the ID of the track point device:
  evdev:
    # Name: ASUE1201:00 04F3:32AE
    # ID: bus 0x18 vendor 0x4f3 product 0x32ae version 0x100

I found that the track point is functional, when i set the
MT_CLS_WIN_8_FORCE_MULTI_INPUT_NSMU class for the reported device.
