[PATCH 3/4] iio: hid-sensor-als: add module alias for autoload

From: Alexander Holler
Date: Wed Jul 10 2013 - 04:33:37 EST


Add a MODULE_DEVICE_TABLE in order to let hotplug mechanisms automatically
load the driver.

This makes it also possible to use the usual driver name instead of
HID-SENSOR-2000xx which isn't very descriptive in kernel messages.
