From 28d5fd860f97f017573c4cd8f199bab867c50a11 Mon Sep 17 00:00:00 2001 From: Daniel Kurtz Date: Wed, 6 Jul 2011 22:57:39 -0700 Subject: [PATCH] Input: synaptics - process button bits in AGM packets AGM packets contain valid button bits, too. This patch refactors packet processing to parse button bits in AGM packets. However, they aren't actually used or reported. The point is to more completely process AGM packets, and prepare for future patches that may actually use AGM packet button bits.
