4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <dan.carpenter@oracle.com>

commit 5ba5b437efaa7a502eec393c045d3bf90c92c4e9 upstream.

We should be allocating enough information for a tiadc_device struct
which is about 400 bytes but instead we allocate enough for a second
iio_dev struct which is over 2000 bytes.
