Subject: [PATCH 4.19 25/30] HID: multitouch: Add support for Google Whiskers Touchpad

From: Marek Maślanka <mm@...ihalf.com>

commit 1d07cef7fd7599450b3d03e1915efc2a96e1f03f upstream.

The Google Whiskers touchpad does not work properly with the default
multitouch configuration. Instead, use the same configuration as Google
Rose.
