From 75255b29d473613e2a5737d6fb368dc4009c90a8 Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Tue, 29 Nov 2011 11:23:27 -0800 Subject: [PATCH] Input: ad7879-i2c - use swapped variant of i2c_smbus_read_word_data This variant was introduced in i2c: boilerplate function for byte swapped smbus_write/read_word_data This also has the side effect of ensuring any errors from the i2c read and no longer mangled.
