Subject: [PATCH 1/4 v3] input: wacom - Scale up touch width and height values for Intuos Pro
Date: Fri, 15 Nov 2013 11:58:24 -0800	[thread overview]
Message-ID: <1384545504-15434-1-git-send-email-pingc@wacom.com> (raw)

From: Signed-off-by: Jason Gerecke <killertofu@gmail.com>

The width and height values reported by the Intuos Pro are not in
surface units as required by the MT protocol. A simple multiplier
of 100x corrects it.
