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


From: Linus Walleij <linus.wall...@linaro.org>

commit 307fe9dd11ae44d4f8881ee449a7cbac36e1f5de upstream.

All the scaling of the KXSD9 involves multiplication with a
fraction number < 1.

However the scaling value returned from IIO_INFO_SCALE was
unpredictable as only the micros of the value was assigned, and
not the integer part, resulting in scaling like this:

$cat in_accel_scale

Fix this by assigning zero to the integer part.
