From 822115ff4bd7141a6069dcc17b35dfd823a44dff Mon Sep 17 00:00:00 2001 From: Daniel Kurtz Date: Tue, 8 May 2012 22:40:26 -0700 Subject: [PATCH] Input: atmel_mxt_ts - do not read extra (checksum) byte atmel_mxt devices will send a checksum byte at the end of a message if the MSB of the object address is set. However, since this driver does not set this bit, the checksum byte isn't actually sent, so don't even try to read it.
