From 987a6c0298260b7aa40702b349282554d6180e4b Mon Sep 17 00:00:00 2001 From: Daniel Mack Date: Mon, 2 Aug 2010 20:15:17 -0700 Subject: [PATCH] Input: switch to input_abs_*() access functions Change all call sites in drivers/input to not access the ABS axis information directly anymore. Make them use the access helpers instead. Also use input_set_abs_params() when possible. Did some code refactoring as I was on it.
