From 5a103e7d6bf05ff4d053ee73a001d255bbc8951a Mon Sep 17 00:00:00 2001 From: Irina Tirdea Date: Mon, 28 Mar 2016 20:15:46 +0300 Subject: [PATCH] iio: gyro: bmg160: fix buffer read values commit b475c59b113db1e66eb9527ffdec3c5241c847e5 upstream. When reading gyroscope axes using iio buffers, the values returned are always 0. In the interrupt handler, the return value of the read operation is returned to the user instead of the value read. Return the value read to the user. This is also fixed in commit 82d8e5da1a33 ("iio: accel: bmg160: optimize transfers in trigger handler").
