Subject: Input: ad7879-i2c - use swapped variant of i2c_smbus_read_word_data
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=75255b29d473613e2a5737d6fb368dc4009c90a8;p=deliverable%2Flinux.git

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.
