[PATCH 4.7 078/184] iio: fix pressure data output unit in hid-sensor-attributes

From: Greg Kroah-Hartman
Date: Thu Sep 22 2016 - 13:51:27 EST


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

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

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

commit 36afb176d3c9580651d7f410ed7f000ec48b5137 upstream.

According to IIO ABI definition, IIO_PRESSURE data output unit is
kilopascal:

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