[PATCH 3.2 078/152] iio: accel: kxsd9: Fix raw read return

From: Ben Hutchings
Date: Sun Nov 13 2016 - 22:06:25 EST


3.2.84-rc1 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.
