[PATCH] iio: fix pressure data output unit in hid-sensor-attributes

From: Kweh, Hock Leong
Date: Sun Aug 28 2016 - 22:49:12 EST


From: "Kweh, Hock Leong" <hock.leong.kweh@xxxxxxxxx>

According to IIO ABI definition, IIO_PRESSURE data output unit is
kilopascal:
http://lxr.free-electrons.com/source/Documentation/ABI/testing/sysfs-bus-iio

This patch fix output unit of HID pressure sensor IIO driver from pascal to
kilopascal to follow IIO ABI definition.
