Subject: iio: adis16400: Set timestamp as the last element in
Date: Fri, 24 Jan 2014 12:24:03 +0100 [thread overview]

Hi,
This patch make sure that the timestamp element is the last element
in the iio_chan_spec.
The index values for the timestamp was hardcoded and
in conflict with other elements (at least on adis16448).
This is a problem in iio_compute_scan_bytes(). The function is
searching for the first element with the timestamp index.
If the found element has a lesser number of storage bits, this
is a potential buffer overflow issue.
