Subject[PATCH v5 2/3] Input: xen-kbdfront - fix multi-touch XenStore node's locations
Date
From: Oleksandr Andrushchenko <oleksandr_andrushchenko@epam.com>

kbdif protocol describes multi-touch device parameters as a
part of frontend's XenBus configuration nodes while they
belong to backend's configuration. Fix this by reading the
parameters as defined by the protocol.

Fixes: 49aac8204da5 ("Input: xen-kbdfront - add multi-touch support")
