Subject: [PATCH 4.4 41/53] iio: imu: adis16480: Fix acceleration scale factor for adis16480

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

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

From: Dragos Bogdan <dragos.bogdan@...log.com>

commit fdd0d32eb95f135041236a6885d9006315aa9a1d upstream.

According to the datasheet, the range of the acceleration is [-10 g, + 10 g],
so the scale factor should be 10 instead of 5.
