Subject: Input: zforce_ts - fix dual touch recognition

From: Knut Wohlrab <[email protected]>

commit 6984ab1ab35f422292b7781c65284038bcc0f6a6 upstream.

A wrong decoding of the touch coordinate message causes a wrong touch ID. Touch ID for dual touch must be 0 or 1.

According to the actual Neonode nine byte touch coordinate coding, the state is transported in the lower nibble and the touch ID in the higher nibble of payload byte five.
