commit f0e84acd7056e6d7ade551c6439531606ae30a46 upstream.

This can result in wrong reference count for trigger device, call
iio_trigger_get to increment reference.

iio:trigger: Introduce iio_tigger_{set,get}_drvdata 2013-03-25T21:06:09+00:00 Lars-Peter Clausen lars@metafoo.de 2013-03-25T08:58:00+00:00 1e9663c62b32f695af37fec4afc473b59f5ca9b4 Introduce iio_tigger_{set,get}_drvdata which allows to attach driver specific data to a trigger. The functions wrap access to the triggers private_data field and all current users are updated to use iio_tigger_{set,get}_drvdata instead of directly accessing the private_data field. This is the first step towards removing the private_data field from the iio_trigger struct.
