[PATCH 4.4 099/146] iio: light apds9960: Add the missing dev.parent

[Greg Kroah-Hartman]

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

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

From: Yong Li <sdliyong@xxxxxxxxx>

commit 590b92a30242dd3f73de3d9a51d9924f1ab33e93 upstream.

Without this, the iio:deviceX is missing in the /sys/bus/i2c/devices/0-0039
Some userspace tools use this path to identify a specific instance of the
device.
