From 5fb17fd9a2d05be77be91369aa2f7b0db42fc8b4 Mon Sep 17 00:00:00 2001 From: Andres Salomon Date: Tue, 11 Nov 2008 09:52:21 -0500 Subject: [PATCH] Input: psmouse - fix incorrect validate_byte check in OLPC protocol The validate_byte check logic was backwards; it should return true for an *invalid* packet. Thanks to Jeremy Katz for spotting this one.
