[PATCH 5.10 03/38] HID: a4tech: use A4_2WHEEL_MOUSE_HACK_B8 for A4TECH NB-95

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

From: Mateusz Jończyk <mat.jonczyk@o2.pl>

[ Upstream commit 9858c74c29e12be5886280725e781cb735b2aca6 ]

This mouse has a horizontal wheel that requires special handling.
Without this patch, the horizontal wheel acts like a vertical wheel.

In the output of `hidrd-convert` for this mouse, there is a
`Usage (B8h)` field. It corresponds to a byte in packets sent by the
device that specifies which wheel generated an input event.

The name "A4TECH" is spelled in all capitals on the company website.
