Subject: [PATCH 4/4] Only report multi-touch when pen is out of range
Date: Thu, 7 Jul 2011 14:05:00 -0700 [thread overview]
Message-ID: <1310072700-2829-4-git-send-email-killertofu@gmail.com> (raw)
In-Reply-To: <1310072700-2829-1-git-send-email-killertofu@gmail.com>
Don't bother evaluating multi-touch packets from the hardware
when the pen is in range. Single-touch is already filtered, but
not MT.
