[PATCH 4.7 066/184] iio: accel: kxsd9: Fix raw read return

[Greg Kroah-Hartman]

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

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

From: Linus Walleij <linus.walleij@xxxxxxxxxx>

commit 7ac61a062f3147dc23e3f12b9dfe7c4dd35f9cb8 upstream.

Any readings from the raw interface of the KXSD9 driver will
return an empty string, because it does not return
IIO_VAL_INT but rather some random value from the accelerometer
to the caller.
