From 423ad0c405d87868bd1ab19e8b503e6a41c86caf Mon Sep 17 00:00:00 2001 From: Hartmut Knaack Date: Thu, 9 Jul 2015 23:51:30 +0200 Subject: iio:light:stk3310: make endianness independent of host Data is stored in the device in be16 format. Make use of be16_to_cpu and cpu_to_be16 to have correct endianness on any host architecture.
