From 83d5f3246fc05a629278240c09688fd9960b97db Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Wed, 11 Dec 2013 18:45:00 +0000 Subject: staging:iio:ad799x fix incorrect endianness specification for buffer elements Due to use of the IIO_ST macro, the endianness element of scan_type was not being set. The result is that it will default to the cpu endianness whereas this driver will fill the buffer with big endian data. Thus for little endian machines, userspace will miss interpret the data.
